Data Sufficiency — Relationships: How is Divya related to Shaloo? Statement I: Divya's mother is the sister of Shaloo's father. Statement II: Shaloo is the daughter of Divya's grandfather's only child. Decide which statement(s) are sufficient to determine the relationship. Choose the correct sufficiency option.

Given

• I: Divya's mother (DM) is sister of Shaloo's father (SF).
• II: Shaloo is the daughter of Divya's grandfather's only child.

Approach
Test each statement independently to see if it yields a unique relationship.

Using Statement I alone
DM and SF are siblings ⇒ children of siblings are cousins.Therefore, Divya and Shaloo are cousins. Statement I is sufficient.

Using Statement II alone
“Divya's grandfather's only child” is Divya's single parent. Shaloo is that person’s daughter ⇒ Shaloo and Divya have the same parent.Therefore, Shaloo is Divya’s sister. Statement II is sufficient.

Conclusion
Each statement independently gives a definite relationship (though different family setups); hence either statement alone is sufficient for the question format.
