Correct Answer: D is the daughter of B


Solution : Given:
C ÷ B – E + A × F – D

As per the given information, the family tree will be as follows –

Here, the quadrilateral represents the male, and the circular figure represents the female in the figure.
Let's check the options –
First option: D is the daughter of B – From the above family tree, it's clear that D is either the daughter or son of A and F. Therefore, this option is incorrect.
Second option: C is the sister of the mother of A – From the above family tree, it's clear that B is the mother of E and E is the brother of A. So, B is the mother of A and E both. So, C is the sister of B, the mother of A. Therefore, this option is correct.
Third option: F is the wife of the son of B – From the above family tree, it's clear that A is the son of B, and F is the wife of A. So, F is the wife of the son of B. Therefore, this option is correct.
Fourth option: B is the mother of A – From the above family tree, it's clear that B is the mother of E and E is the brother of A. So, B is the mother of A and E both. Therefore, this option is correct.

So, only the first option does not fulfill the relation as per the family tree. Hence, the first option is correct.
