Answer is Wrong!
Answer is Right!
The correct answer is: B. X is the sister of Z.
Explanation:
- A is the father of X.
- B is the mother of Y.
- The sister of X is Z and Y.
From the above information, we can infer that:
- X and Z are siblings.
- Y is the brother of X and Z.
- B is the mother of X and Z.
- A is the father of X and Z.
Therefore, the statement “X is the sister of Z” is definitely not true.
