• A. N β P - L + E - M
• B. N - Y + A β M
• C. M - Y * P - N
• D. N β C + F * M

Answer 1

The correct option is A

N β P - L + E - M

N $\beta$ P $\to$ N is the brother of P

P - L $\to$ P is the sister of L

L + E $\to$ L is the mother of E

E - M $\to$ E is the sister of M.

Hence, L is the mother of M, P is the maternal aunt of M and N is the maternal uncle of M.
