A family has P, Q, R, S, T. P is the mother of Q. Q is the sister of R. S is the husband of P. T is the only child of R. How is S related to T?
S is T's grandfather. P is the mother of Q, and Q and R are siblings, so S, as P's husband, is father to both R and Q. T is R's child, so S is two generations above T.

- BFather
- CUncle
- DGreat-grandfather
Explanation
P is mother of Q and R (siblings), and S is P's husband, so S is the father of Q and R. T is the child of R. Hence S is T's grandfather. The only wrong step to avoid is treating S as T's father, which would skip a generation.
