Decoding the Symbols:
Symbol | + | - | × |
---|---|---|---|
Meaning | A is daughter of B (A is female) | A is husband of B (A is male, B is female) | A is brother of B (A is male) |
Let's analyze each statement:
1) A + B + C
- This sequence is logically possible. A is the granddaughter of C, and B is the daughter of C.
2) A - C × C
- A - C: A is husband of C (A is male, C is female).
- C × C: C is brother of C. This part of the statement implies that a person is their own brother, which is logically impossible.
3) A - B + C
- This sequence is logically possible. A is the son-in-law of C, and B is the daughter of C.
4) A + B - C
- This sequence is logically possible. A is the daughter of B, and B is the husband of C. So, A is the daughter of B and C.
The statement that does not hold is 'A - C × C' because 'C is brother of C' is a self-contradictory and impossible relationship.
Hence, the correct answer is "Option 2".
