Understanding the Relationships
To determine the correct expression indicating that U is the father-in-law of P, we need to analyze the given codes and their meanings. Here's a breakdown of the symbols:
- A $ B: A is the brother of B
- A @ B: A is the wife of B
- A # B: A is the daughter of B
- A * B: A is the father of B
Now, let's evaluate option A step-by-step.
Breaking Down Option A: P @ Q $ T # U * W
1. P @ Q:
- P is the wife of Q.
2. Q $ T:
- Q is the brother of T.
3. T # U:
- T is the daughter of U. This implies U is the parent of T.
4. U * W:
- U is the father of W.
Now, let's summarize the relationships:
- P is the wife of Q.
- Q is the brother of T.
- T is the daughter of U, meaning U is T's father.
- Since Q is T's brother, U is also the father of Q.
Conclusion
Since P is married to Q, and U is the father of Q, it follows that U is the father-in-law of P.
Thus, the correct answer is option A, confirming that U is indeed the father-in-law of P.
Key Point Summary
- P is married to Q.
- Q is a sibling to T, whose parent is U.
- Therefore, U is P’s father-in-law.
