• A.
  $K\times N\$J+F$
• B.
  $F\times J+N\$K$
• C.
  $N+K\times F\$J$
• D.
  $K\$N\times J+F$

Answer 1

The correct option is D

$K\$N\times J+F$

• $K\times N\$J+F\to$ $K$ is the sister of $N,N$ is the father of $J,J$ is the brother of $F$. Here, $J$ is the son of $N$ and so, $K$ will be his aunt.
• $F\times J+N\$K\to$ $F$ is the sister of $J,J$ is the brother of $N,N$ is the father of $K$. Here $K$ is J’s father’s/mother’s brother or Uncle.
• $N+K\times F\$J\to$ $N$ is the brother of $K,K$ is the sister of $F,F$ is the father of $J$. Again, K is J’s father’s sister.
• $K\$N\times J+F\to$ $K$ is the father of $N,N$ is the sister of $J,J$ is the brother of $F$. These statements together mean that $K$ is the father of $J$.
