**Soln.**

**Ans: d**

M + K ÷ T × P shows the required relationship as explained below:

- T × P means T is the sister of P.
- K ÷ T means K is the father of T. Hence, from information (i), K is also the father of P.
- M + K means M is the brother of K. Therefore, using information (ii), we find that M is the uncle of P.
