Explanation:

- R # P = S # Q + J (?) T:

- R is the mother of P.

- P is the sister of S.

- S is the mother of Q.

- Q is the brother of J.

- We need J to be a child of T.

- R % M @ S % T:

- R is the wife of M.

- M is the father of S.

- S is the wife of T.

Given that S is the wife of T, J can be either their son or daughter. This means that either P & Q or P * Q can satisfy J being a child of T.

- Option 1 (&): J is the son of T.

- Option 2 (*): J is the daughter of T.

- Answer: Either 1 or 2 is correct given J can be either son or daughter of T.
