In a family tree, P is the father of Q, Q is the sister of R, and R is the father of S. How is P related to S?
P is the grandfather of S. Since Q and R are siblings, P is the father of both. R is S's father, so P is the father of S's father, which makes P the paternal grandfather of S.

- BFather
- CUncle
- DGreat-grandfather
Explanation
P is the father of Q, and Q is the sister of R, so P is also the father of R. R is the father of S, so P is the father of S's father. That makes P the paternal grandfather of S. Calling P the father would skip a generation, which is the mistake in that option.
