- BP
- CQ
- DR
Explanation
- P and S are unmarried students. This means they are not the doctor, lawyer, or artist. So, P and S are not the doctor.
- Q is explicitly stated to be neither doctor nor artist. So, Q is not the doctor.
- R is explicitly stated to be not a doctor. So, R is not the doctor.
- From the five persons (P, Q, R, S, T), P, S, Q, and R have all been eliminated as possibilities for the doctor.
- Therefore, by elimination, T must be the doctor.
