Which of the following is a pair of husbands ?
Answer: D
P is a photographer.
P is married to S. So, one couple is PS. Then, the other couple is RQ.
S is a reporter.
The writer is married to Q. So, R is the writer. Now, P, Q, R, S have different professions. So, Q is a technician and thus U is also a technician.
U is the brother of R.
We now know the professions of P, Q, R, S and U. Only T remains. Since there are two reporters in the group, so T is also a reporter.
Hence, The sex of P, Q, R, S is not given. So, the pairs of husbands cannot be determined.
