Important Points

  • The question is asking about D's relation with F.
  • For this, we must know the gender of D.

Statement I: B has two sisters E and F.

Data suff Nitya Shrivastav 30Oct20 pankaj chaudhary D9

We cannot say how D is related to F using this statement.

Statement II: A is the mother of B, who Is the brother of D.

Data suff Nitya Shrivastav 30Oct20 pankaj chaudhary D10

We cannot say how D is related to F using this statement.

Combining both statements, we get:

Data suff Nitya Shrivastav 30Oct20 pankaj chaudhary D11

We cannot say how D is related to F because we don’t know the gender of D.

Hence, ‘Statement I and II together are not sufficient is the correct answer.

Mistake Points'B has two sisters E and F.' doesn't specify that B has only 2 sisters. Had the word only been given in the sentence, we could have concluded that D.
