Understanding the Relationships
To solve how D is related to A, we need to clarify the relationships step by step based on the given information:
- A is the brother of B: This establishes that A and B are siblings.
- B is the sister of C: This means C is also a sibling to A and B, making A, B, and C a trio of siblings.
- C is the father of D: This indicates that D is the child of C.
Analyzing the Relationship
Now, let's analyze the relationship between A and D:
- Since A, B, and C are siblings, it follows that A is the uncle of D because:
- C (D's father) is A's brother (since A and C are siblings).
- Therefore, D is A's niece or nephew, depending on D's gender.
However, since the question asks how D is related to A in a general sense, we cannot determine the specific gender of D from the information given.
Conclusion
The relationship can be summarized as follows:
- D is A's niece or nephew.
- Since the question does not specify the gender of D, we conclude that:
Answer: D cannot be determined specifically as either brother or sister, hence option 'D' is correct.
