• A. Uncle
• B. Father
• C. Brother-in-law
• D. Brother

Hint:

Use symbols to draw family trees quickly:
- Use double horizontal lines ($=$) for marriage.
- Use single horizontal lines ($-$) for siblings.
- Use vertical lines ($|$) for generations.
- Use $+$ for male and $-$ for female.
This visual mapping prevents any logical errors.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This is a blood relation logical puzzle.
We need to map out a family tree containing three generations based on the relationships given in the text.
Once the family tree is constructed, we can easily find the relation between R and B.

Step 2: Detailed Explanation:

• Analyze the First Generation:
- "P, S are married couple": This establishes a marriage relation between P and S.
- "S is mother of B": This tells us that S is Female ($S^{-}$), which means P must be Male ($P^{+}$).
P and S are the parents of B.

• Analyze the Siblings (Second Generation):
- "Q is daughter of P": Since P and S are married, Q is also the daughter of S.
This means Q ($Q^{-}$) and B are siblings.
- "R is husband of Q": This means R ($R^{+}$) is married to Q.
Therefore, R is the son-in-law of P and S, and the brother-in-law of Q's sibling, B.

• Analyze the Third Generation:
- "S is grandmother of V and Q is aunt of V":
Since Q is the aunt of V and sister of B, V must be the child of B.
This is consistent with S being the grandmother of V.

• Determine the Relation between R and B:
- Q and B are siblings.
- R is married to Q (R is Q's husband).
- Therefore, R is the brother-in-law (sister's husband) of B.

Step 3: Final Answer:
R is the brother-in-law of B.
Thus, the correct option is (C).
