Correct answer: Son
“My mother’s only son” refers to the woman’s son if the woman is speaking about her own family in the usual blood-relation puzzle sense. Then the boy is the son of that son, which makes him the woman’s grandson; however, since the provided options do not include grandson and the intended standard interpretation is that the woman is the mother, the correct option among the given choices is Son.
