Show answer & explanation
Correct answer: D
Final answer: Neither statement is sufficient to determine how many children M has.
From the statement that H is the only daughter of X, who is the wife of M, we deduce that H is a daughter of M. This tells us M has at least one child (a daughter) but does not rule out any sons, so the total number of children remains unknown.
The statement that K and J are brothers of M gives information about M's siblings, not about M's children, so it provides no information about the number of children.
Combining both pieces of information still leaves open whether M has any sons, so the exact number of children cannot be determined.
