FirstInTest · Accepted Answer

Let's deduce the relationships:
1.  J is sister of K $\Rightarrow$ J = female.
2.  K is sister of L $\Rightarrow$ K = female. L's gender is not specified yet.
3.  L is sister of M $\Rightarrow$ L = female. M's gender is not specified yet.
4.  M is brother of N $\Rightarrow$ M = male. N's gender is not specified yet.

From these, we know: J (female), K (female), L (female), M (male).
N's gender is unknown.

Now let's check the statements:
(A) K and L are sisters. (K=female, L=female). This is True (necessary).
(B) M and N are brothers. (M=male). N's gender is not given, so we cannot confirm N is male. This statement is Not necessarily true.
(C) L is sister of N. (L=female). Since M is L's brother and M is N's brother, L and N are siblings. So L is N's sister. This is True (necessary).
(D) J, K, L are females and M is male. (J=female, K=female, L=female, M=male). This is True (necessary).

The statement that is not necessarily true is (B).
