Shyam said Deepak's mother is the mother of my father's wife. How is Deepak related to Shyam?

Mother's brother

The correct answer is Option (1) → Mother's brother

Let's analyze the statement:

"Deepak's mother is the mother of my father's wife."

1. "My father's wife" refers to Shyam's mother.
2. "The mother of my father's wife" would therefore refer to Shyam's maternal grandmother.

So, Shyam is saying that Deepak's mother is Shyam's maternal grandmother.

If Deepak's mother is Shyam's maternal grandmother, then Deepak must be Shyam's mother's brother, as he would be the son of Shyam's maternal grandmother.

Thus, Deepak is Shyam's Mother's brother.
