Statement II: Dev is the son of Shashank, who is the father of Gargi.

Explanation:

From statement I, we know Maya is Gargi's mother.

From statement II, we know Shashank is Gargi's father and Dev is Shashank's son.

Combining both statements,

We can deduce that Maya and Shashank are Gargi's parents, and therefore, Dev is Gargi's brother.

Since Maya is Gargi's mother, Dev is Maya's son.

Both statements are needed to determine the relationship between Dev and Maya.

∴ Both statements I and II are needed to answer the question.

Hence the correct answer is "Option 4"
