Show the answer and explanation
CorrectNot quiteAnswer B
Correct answer: B
Explanation
The elderly woman T and the son's wife S are female.
P, U and R are male (father-in-law, husband, brother).
Q is a grandchild, but no clue says whether Q is a boy or a girl, so Q cannot be counted.
Definitely female: T and S, that is, 2.
Worth noting
3 assumes Q is a girl because R is called Q's brother. 'Brother' fixes R's gender, not Q's.
