Pointing to a woman, a man says, 'Her mother is the only daughter of my mother.' How is the woman related to the man?

The woman is the man's daughter. Since the man's mother's only daughter is the woman's mother, the woman's mother is the man's sister. This makes the woman the sister's daughter, hence the man's niece.

Explanation

The man's mother has only one daughter, which is the woman's mother. So the woman's mother is the man's sister. Therefore, the woman is the man's niece. The key distractor (Sister) misses the generational difference between the man and the woman he is pointing to.
