‘A + B’ means ‘A is the brother of B’
‘A - B’ means ‘A is the mother of B’
‘A $$\times$$ B’ means ‘A is the husband of B’
‘A $$\div$$ B’ means ‘A is the sister of B’
‘A # B’ means ‘A is the daughter-in-law of B’
If ‘C − M + S + K $$\times$$ R # T’, then which of the following statements is NEVER correct?

C is the mother of M, who in turn is the brother of S, who in turn is the brother of K, who in turn is the husband of R, who in turn is the daughter-in-law of T. 

Option A can never be possible as S is the brother of C's son. 

Option B is true as K and M both are brothers of S. It means that both K and M are brothers. 

Option C can be true if T is male. So, it can't be rejected entirely. 

Option D is true as R is the wife of K, who in turn is a brother of M.

Hence, Option A can never be true.
