Hint:

Always simplify kinship puzzles by mentally putting yourself in the narrator's shoes! Ask yourself: "Who is my grandfather's only son?" $\rightarrow$ That is my Dad. "Who is the daughter of my Dad?" $\rightarrow$ That is my sister! Breaking the phrase down into personal terms solves the mystery instantly.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Blood relation problems are best cracked by breaking down complex descriptions into distinct generational steps. By reading the relationships backward starting from the reference person ("my..."), we can simplify each phrase step-by-step to reveal the direct connection.

Step 2: Key Formula or Approach:
Deconstruct the descriptive statement step-by-step: $$\text{"My grandfather's only son"} \rightarrow \text{Identify Person A}$$ $$\text{"Daughter of Person A"} \rightarrow \text{Identify Target Woman}$$

Step 3: Detailed Explanation:
Let's decode Ravi's description statement from the inside out: 1. First Segment: Identify "my grandfather's only son" from Ravi's perspective. Ravi's paternal grandfather has only one son. The only son of one's grandfather must be one's own Father. Therefore, this phrase simplifies directly to Ravi's Father. 2. Second Segment: Now substitute this back into the remaining part of the sentence: "She is the daughter of [Ravi's Father]." The daughter of Ravi's father is someone who shares the exact same parents as Ravi. Therefore, the woman must be Ravi's Sister. This straightforward generational mapping confirms that the woman is Ravi's sister, which matches option (a).

Step 4: Final Answer:
The woman is related to Ravi as his Sister.
