Hint:

Carefully use the given symbols and understand their relations to form the correct family relationship.

Answer 1

The Correct Option is A

We know that: - ‘+’ means son, - ‘\(\times\)’ means brother, - ‘-’ means sister. The expression ‘A + B \(\times\) D - C’ means that: - A is the son of B, - B is the brother of D, - C is the sister of D, which makes A the nephew of D.
