• D. None of these

Answer 1

Answer: (A)

N $\beta$ P $\square$ L $\Delta$ E $\square$ M

Here the question ask for maternal uncle ,this relationship is stablished from mothers side relations.

now in option A

N $\beta$ P show that N is brother of P

P $\square$ L show that P is the sister of L

here relation established that N is the brother of L

L $\Delta$ E show that L is mother of E

E $\square$ M show that E is sister of M

So, L is also mother of M from the relation we have found that N is brother of L.

Thus, N is the maternal uncle of M.

Hence, the answer is N $\beta$ P $\square$ L $\Delta$ E $\square$ M.
