• B. Only (B)
• C. Only (C)
• D. None of these

Answer 1

The correct option is B

Only (B)

(A) `K $\times$ P $÷$ M $\times$ Q' means `K is the brother of P whose father is M, who is the brother of Q' Thus, K is the child of M, who is the brother of Q. So, Q may be the paternal uncle or aunt of K.

(B) `K $\times$ B $÷$ N $\times$ Q$\times$D' means `K is the brother of B, whose father is N, who is the brother of Q who in turn is the brother of D'. Thus, N is the father of K and Q is the brother of N. So, Q is the paternal uncle of K.

(C) `Q $\times$L$÷$R$\times$K' means `Q is the brother of L whose father is R, who is the brother of K'. Thus, R is the father of Q and R is the brother of K. So, K may be the paternal uncle or aunt of Q.

Thus, only (B) represents the correct relation.
