Solution
Let's break down the information given:
i. There are 2 lecturers, 2 singers, 1 doctor, 1 engineer in a group of 6 people A, B, C, D, E and F.
ii. The doctor C is married to A, who is a lecturer. So, C is a doctor and A is a lecturer.
iii. The engineer is married to B who has the same profession as that of E. So, B and E are lecturers and the engineer is married to B, so the engineer is F.
iv. C, A, B and F are married couples and nobody in this group has the same profession. So, C is married to A (doctor and lecturer) and B is married to F (lecturer and engineer).
v. E is F’s brother. So, E is a lecturer and F's brother.
From the above information, we know that A and C are a lecturer and a doctor, B and F are a lecturer and an engineer, and E is a lecturer. This leaves D as the only person whose profession we don't know. Since there are 2 singers and all other professions are accounted for, D and the remaining person must be the singers. The remaining person can't be A, B, C, E or F, so it must be B.
So, the pair of singers is B and D.
However, this option is not given in the choices. There seems to be a mistake in the question or the options provided.
