Pointing to a photograph Arun said, “She is the mother of my brother’s son’s wife’s daughter.” How is Arun related to the lady?
None of these
One’s brother’s son’s wife’s daughter implies paternal granddaughter of one’s brother. The mother of paternal granddaughter's brother implies wife of one’s nephew.
So, it can be concluded that Arun is the paternal uncle of the female’s husband.
