Family tree

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

qImage682dac311a145e06390c1f34

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

qImage682dac321a145e06390c1f36

This sequence is logically possible. A is the son-in-law of C, and B is the daughter of C.

4) A + B - C

qImage682dac321a145e06390c1f38

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".
