................. is the cousin of M in the family tree given below.

Explanation Option [c] is correct because we know that sons/daughters of father's brother are cousins. In this case, D is the son of P and M is the son of Q while P and Q. are brothers. Clearly, D and M are cousins. Rest of the options is incorrect because of the correctness of option [c]. Note: Another pair of cousins is LA.
