A + B × C Expression Analysis
We are given the expression A + B × C and need to find the relationship between A and C.
Decoding B × C Relation
Let's analyze the second part of the expression, B × C:
- Based on the definition X × Y, B × C means B is the brother of C.
This establishes that B and C are siblings. We know B is male.
Decoding A + B Relation
Now, let's analyze the first part of the expression, A + B:
- Based on the definition X + Y, A + B means A is the daughter of B.
This tells us that A is female and B is her parent.
Relationship Determination: A and C
Combining the deduced relationships:
- A is the daughter of B.
- B is the brother of C.
Since B is the sibling of C, and A is the child of B, it follows that C is the sibling of A's parent (B). Therefore, C is the uncle or aunt of A.
As A is confirmed to be female (daughter), A is the niece of C.
Options Evaluation for A and C
Let's examine the given options based on our findings:
- Option 1: A is niece of C - This aligns perfectly with our conclusion.
- Option 2: A is daughter of C - This is incorrect because A is the daughter of B, not C.
- Option 3: A is the cousin of C - This is incorrect. Cousins are children of parents' siblings, while A is the child of a sibling.
- Option 4: A is the daughter-in-law of C - This suggests marriage into the family, which is not implied by the given relations.
Final Conclusion on A's Relation
After analyzing the expression A + B × C using the provided symbol definitions, the only true statement is that A is the niece of C.
