Read the following information carefully and answer the given questions. 'G % H' means 'G is the husband of H'. 'G @ H' means 'G is the wife of H'. 'G # H' means 'G is the sister of H'. 'G * H' means 'G is the brother of H'. 'G = H' means 'G is the mother of H'. 'G + H' means 'G is the father of H'. 'G ^ H' means 'G is the son of H'. 'G ≠ H' means 'G is the daughter of H'. Example: G 2% H means G is the husband of H and G has two siblings. The following is the family of Y, a married person: N 2+ P, O 1% D, A 0@ N, D 0= T, C 2# T, M 1^ A, Y 1* O, S 0≠ B, E 1* R, F 0^ R, R 1% C How S is related to O?

### Concept & Logic In this coded blood relations problem, each symbol represents a specific relationship, and the preceding number indicates the count of siblings the first person has. By piecing together specific parts of the string, we can build the relevant branches of the family tree without solving the entire puzzle. ### Step-by-Step Solution 1. **Analyze the target relationship:** We need to find the link between $S$ and $O$. Let's trace the connections involving these characters. 2. **Decode $O$'s immediate connections:** * `O 1% D` means $O$ is the husband of $D$. $O$ is male and has 1 sibling. * `Y 1* O` means $Y$ is the brother of $O$. $Y$ has 1 sibling. Since $O$ has 1 sibling and $Y$ is his brother, $Y$ and $O$ are the two siblings. 3. **Decode $S$'s immediate connections:** * The problem states $Y$ is a "married person". * `S 0≠ B` means $S$ is the daughter of $B$. $S$ has 0 siblings. * Since $Y$ is married and $S$ is the only child of $B$, $B$ must be $Y$'s wife. Therefore, $S$ is the daughter of $Y$ and $B$. 4. **Establish the final link:** * $Y$ is the brother of $O$. * $S$ is the daughter of $Y$. * The daughter of one's brother is a niece. Therefore, $S$ is the niece of $O$. ### Exam Strategy & Shortcut **Targeted Tracing:** Do not waste time drawing the entire complex family tree (involving $N$, $C$, $R$, etc.) unless a question specifically asks for it. Scan the string for the letters in question ($S$ and $O$) and find the shortest path connecting them ($S \rightarrow B \rightarrow Y \rightarrow O$). ### Common Pitfall A common mistake is getting overwhelmed by the sheer length of the family string and attempting to map it all out sequentially from left to right, which burns crucial time. ### Final Answer Therefore, the correct answer is **Niece**.
