Answer:
Option D
Explanation:
T is the mother-in-law of P and P is the wife of R. So, R is P's husband and T is mother of R. So, one couple is RP. Since S is the father of U, so S is the husband of T. So, the other couple is ST.
Since Q is the sister of U, so R, U and Q are children of S and T. Since there are 3 gents in all, so U is also a male. Now, Q reads Navbharat Times; U reads Hindustan Times; T reads Indian Express. Since S does not read. The times of India or The Tribune, so S reads Business Herald. . Since R does not read The Tribune, so R reads The Times of India. Clearly, P reads The Tribune
The two coupl6s are - RP and ST
