Q: How is Zara related to Vani? I. Vani is the brother of Uma, who is the daughter of Zar

Correct Answer: Option D (Both statements I and II together are not sufficient.). From Statement I: Vani and Uma are siblings, and Zara is their parent. So Vani is the son of Zara. However, we do not know Zara's gender. Zara could be the father or mother. From Statement II: It only gives the number of children. Combining both still does not reveal Zara's gender. Both statements together are not sufficient.

Correct Answer: Option C (Both statements I and II together are necessary.). From Statement I: 'good' could be 'alpha' or 'beta'. Not sufficient. From Statement II: Deals with 'water' and 'life'. Not sufficient. Combining I and II: The common word is 'water' and the common code is 'beta'. Therefore, 'water' = 'beta'. This leaves 'good' = 'alpha' in the first statement. Both statements are necessary.
