Explanation

Here's a step-by-step deduction: 1. Identify known professions and relationships: * A = Engineer. * F = Draughtsman, son of B, brother of E. * E = Doctor, unmarried. * C = Lawyer, daughter-in-law of D. * D = Grandmother of F. 2. From "D is grandmother of F" and "F is son of B", we deduce that D is a parent of B. * Since C is "daughter-in-law of D", C must be married to D's son. * Combining these, C is married to B. This means B is D's son and the father of F. * So, B is male. 3. Use the marriage information: * There are two married couples: (Engineer, Stenographer) and (Judge, Lawyer). * We know C is the Lawyer and is married to B. Therefore, B must be the Judge. * So, C = Lawyer (female) and B = Judge (male). 4. List assigned professions: * A = Engineer * B = Judge * C = Lawyer * E = Doctor * F = Draughtsman 5. The only remaining member is D, and the only remaining profession is Stenographer. Therefore, D must be the Stenographer. 6. Verify with the first marriage: "A, the engineer is married to the lady stenographer." This confirms A (Engineer) is married to D (Stenographer), which fits perfectly as D is female and the only remaining profession for her is Stenographer. Thus, the profession of D is Stenographer. The final answer is B) Stenographer.
