• A. Sister
• B. Mother
• C. Wife
• D. Mother in law

Thus, X is the wife.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
To solve family relationship riddles, we should break down the descriptive statement from the end and trace the relations step-by-step.

Step 2: Detailed Explanation:
Let us analyze the description given by X regarding Y's relationship:
- "father of my father": This refers to X's paternal grandfather.
- "only granddaughter of the father of my father": This refers to the only granddaughter of X's paternal grandfather.
Let us determine who this "only granddaughter" could be:
- If X is a female, then the only granddaughter of her grandfather must be X herself (or her sister, but since she is the "only" granddaughter, it must be X).
- If X is a male, then the only granddaughter of his grandfather would be X's sister.
- Now, let us analyze the next part of the phrase: "He [Y] is the husband of the only granddaughter_____"
Substituting the granddaughter with X:
"Y is the husband of X."
If Y is the husband of X, then X is the Wife of Y.
Checking the options:
- (A) Sister
- (B) Mother
- (C) Wife
- (D) Mother-in-law
Since "Wife" is one of the options, this confirms the assumption that X is female and is referring to herself as the only granddaughter.
Thus, X is related to Y as his Wife.

Step 3: Final Answer:
X is related to Y as his Wife.
