A, B, C, D, E, F and G are Lecturers from different cities—Hyderabad, Delhi, Shillong, Kanpur, Chennai, Mumbai and Srinagar (not necessarily in the same order) who participated in a conference. Each one of them is specialized in a different subject, viz., Economics, Commerce, History, Sociology, Geography, Mathematics and Statistics (not necessarily in the same order). Further 1. Lecturer from Kanpur is specialized in Geography 2. Lecturer D is from Shillong 3. Lecturer C from Delhi is specialized in Sociology 4. Lecturer B is specialized in neither History nor Mathematics 5. Lecturer A who is specialized in Economics does not belong to Hyderabad 6. Lecturer F who is specialized in Commerce belongs to Srinagar 7. Lecturer G who is specialized in Statistics belongs to Chennai Who is specialized in Geography?

This is a logic puzzle that requires matching Lecturers, Cities, and Subjects. Let's break down the information step-by-step:

Known facts from the statements:

1. C is from Delhi and specialized in Sociology. (C -> Delhi -> Sociology)
2. D is from Shillong. (D -> Shillong)
3. F is from Srinagar and specialized in Commerce. (F -> Srinagar -> Commerce)
4. G is from Chennai and specialized in Statistics. (G -> Chennai -> Statistics)
5. A is specialized in Economics and does not belong to Hyderabad. (A -> Economics, A != Hyderabad)
6. B is specialized in neither History nor Mathematics. (B != History, B != Mathematics)
7. The Lecturer from Kanpur is specialized in Geography. (Kanpur -> Geography)

Let's list the remaining Lecturers, Cities, and Subjects after assigning the known facts:

• Assigned Lecturers: C, D, F, G (A is partially assigned)
• Remaining Lecturers to fully assign: A, B, E
• Assigned Cities: Delhi, Shillong, Srinagar, Chennai
• Remaining Cities: Hyderabad, Kanpur, Mumbai
• Assigned Subjects: Sociology, Commerce, Statistics (Economics is assigned to A)
• Remaining Subjects: History, Geography, Mathematics

Now let's use statement 7: "The Lecturer from Kanpur is specialized in Geography."

• Lecturer A is specialized in Economics, so A is not Geography.
• Lecturer D is from Shillong, so D is not from Kanpur.
• Therefore, the (Kanpur -> Geography) pair must be assigned to either Lecturer B or Lecturer E.

Let's consider these two possibilities:

Possibility 1: Lecturer B is from Kanpur and specialized in Geography.

• This is consistent with statement 6 (B is neither History nor Mathematics, and Geography is neither of those).
• So, B -> Kanpur -> Geography.

Now, let's update the remaining items:

• Lecturers to fully assign: A, D, E
• Remaining Cities: Hyderabad, Mumbai (Kanpur is assigned to B)
• Remaining Subjects: History, Mathematics (Geography is assigned to B)

From statement 5: A is specialized in Economics and does not belong to Hyderabad.

• Since the only remaining cities for A are Hyderabad and Mumbai, A must be from Mumbai.
• So, A -> Mumbai -> Economics.

Now, we have Lecturers D and E left, with City Hyderabad and Subjects History and Mathematics.

• D is from Shillong (given).
• Therefore, E must be from Hyderabad. (E -> Hyderabad)
• The remaining subjects (History, Mathematics) must be assigned to D and E.
  • If D is History, then E is Mathematics.
  • If D is Mathematics, then E is History. This completes the puzzle without any contradictions.

Possibility 2: Lecturer E is from Kanpur and specialized in Geography.

• So, E -> Kanpur -> Geography.

Now, let's update the remaining items:

• Lecturers to fully assign: A, B, D
• Remaining Cities: Hyderabad, Mumbai (Kanpur is assigned to E)
• Remaining Subjects: History, Mathematics (Geography is assigned to E)

From statement 5: A is specialized in Economics and does not belong to Hyderabad.

• A must be from Mumbai.
• So, A -> Mumbai -> Economics.

Now, we have Lecturers B and D left, with City Hyderabad and Subjects History and Mathematics.

• D is from Shillong (given).
• Therefore, B must be from Hyderabad. (B -> Hyderabad)
• The remaining subjects (History, Mathematics) must be assigned to B and D.
  • B's subject must be either History or Mathematics.
• However, statement 6 clearly says: "Lecturer B is specialized in neither History nor Mathematics."
• This creates a contradiction, as B must be one of these subjects. Therefore, Possibility 2 is incorrect.

Conclusion: Possibility 1 is the only valid solution. In this scenario, Lecturer B is from Kanpur and specialized in Geography.

The question asks: "Who is specialized in Geography?" Based on our valid solution, B is specialized in Geography.

The final answer is A) B
