Solution (By Examveda Team)

Let's break down this blood relation question step-by-step to understand it easily.

Step 1: Understand the first statement.
"A and B are brothers."
This tells us that A is male and B is male. They share the same parents.

Step 2: Understand the second statement.
"C and D are sisters."
This tells us that C is female and D is female. They share the same parents.

Step 3: Connect the families using the third statement.
"A's son is D's brother."
Let's imagine A has a son. For clarity, let's call him Son-of-A.
The statement says this Son-of-A is D's brother.
Since C and D are sisters (from Step 2), if Son-of-A is D's brother, then Son-of-A is also C's brother.
This means Son-of-A, C, and D are all siblings (they have the same parents).
We know Son-of-A is A's son. So, A is the father of Son-of-A.
Since Son-of-A, C, and D are siblings, this means A is also the father of C and D.

Step 4: Find the final relationship.
We need to find: "How is B related to C ?"
From Step 3, we know that A is C's father.
From Step 1, we know that A and B are brothers.
If A is C's father, and B is A's brother, then B is C's father's brother.
A father's brother is called an Uncle.

So, B is C's Uncle.

Therefore, the correct option is Option C: Uncle.
