Blood Relations

Step 1: Understanding the Concept:
This is a logical reasoning problem based on blood relations. The goal is to decode the statement made by Manu to identify the relationship between Manu and the person in the portrait.

Step 2: Detailed Explanation:
Let's break down Manu's statement into parts to analyze it systematically.
Part 1: "I have no brother and sister."
This is a crucial piece of information. It establishes that Manu is an only child.
Part 2: "...my father's son..."
Since Manu has no brother, the only son of his father is Manu himself.
Part 3: "...the wife of my father's son..."
Substituting the deduction from Part 2, this phrase becomes "the wife of Manu," which is simply Manu's wife.
Part 4: "Her mother is the wife of my father's son..."
The word "Her" at the beginning of the statement indicates that the person in the portrait is a female. Let's call the person in the portrait 'P'. The statement now reads: "P's mother is Manu's wife."
Conclusion:
If the mother of the person in the portrait (P) is Manu's wife, then P must be Manu's child. Since we already established that P is a female ("Her mother"), the person in the portrait is Manu's daughter.

Step 3: Final Answer:
Manu was looking at the portrait of his daughter. Therefore, option (D) is the correct answer.

Let's map out the family relationships based on the given statements.
1. A is the brother of B. (A and B are siblings, A is male).
2. C is the father of A. (This means C is also the father of B).
3. E is the daughter of B. (B is the parent of E).
4. D is the brother of E. (This means D is also a child of B, and D is male).
So, D and E are children of B. The question asks for the uncle of D. The uncle is the brother of one's parent. D's parent is B. We need to find the brother of B. From statement 1, we know that A is the brother of B. Therefore, A is the uncle of D.

Let's break down the statement:
- "The father of my sister's brother" refers to Anjali's father because her sister's brother is Anjali's brother, and their father would be the same.
- "He is the only son of the father of my sister's brother" means he is Anjali's brother (the only son of Anjali's father).
Therefore, the person Anjali is pointing to is her brother, not a cousin or any other relative.
Thus, the correct answer is (d) None of these.
