‘A + B’ means ‘B is the father of A’
‘A – B’ means ‘B is the mother of A’
‘A @ B’ means ‘B is the brother of A’
‘A * B’ means ‘B is the son of A’

Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Mother-in-law.
In the diagram shown;
The square shows males, the circle shows females, vertical lines show generations, a single horizontal line shows brothers or sisters, and double lines show a couple.
