Correct answer: A
Concept
In a blood-relation puzzle, fix each person's gender and link every stated relationship into a single family chain. A key identity here: if two people are husband and wife, then the child of one of them is also the child of the other; so the child of a person's spouse is that person's own child.
Application
O is the husband of P, so O and P are a married couple and O is male.
M is the son of P. Because O is P's husband, M is the child of O's wife, which by the identity above makes M a child of O too.
M is described as a son, i.e. male, so M is the male child of O. Therefore M is the son of O.
Cross-check
Q being the granddaughter of O is extra information about O's descendants and does not change the M-to-O link; it only confirms O is the head of the family. Reading the chain back the other way, O (P's husband) is the father of M, which is consistent with M being O's son. So the relation of M to O is Son.
