Correct Solution: Option C

Step-by-step Solution:

Analysis of the Statements

  • Statement 1: (Sufficient)

    This statement tells us Rahul > Deepak and Rahul > Vinod. It also states Manoj > Rahul. By combining these, we get a clear, complete order for the heaviest person: Manoj > Rahul. This definitively shows that Manoj is the heaviest. Therefore, this statement alone is sufficient.

  • Statement 2: (Not Sufficient)

    This statement tells us Rahul > Deepak, Manoj > Deepak, and Deepak > Vinod. This establishes that both Rahul and Manoj are heavier than Deepak, but it provides no information to compare Rahul and Manoj directly. We cannot determine who is the heaviest from this statement alone.


Conclusion: Statement I alone is sufficient to answer the question, while Statement II alone is not.

Final Answer: The correct option is C.
