Answer: Father.
The idea
The spouse of a parent is the other parent. Two short steps and the relation is settled.
Shortcut. The husband of a boy's mother is his father: Q is P's husband and P is R's mother, so Q is R's father.
Common trap. "Son" — answering in the reverse direction: R is Q's son, but the question asks what Q is to R.
