The correct option is
D If the data even in both statements I and II together are not sufficient to answer the question.
From Statement 1 : The situation can be depicted as below,
Ramakant, _ , _ , _ , Chandrakant, Suresh
Hence, Nothing can be said about who is on the left of Ramakant.
From Statement 2 : The situation can be depicted as below,
Ramakant, _ , _ , Suresh, _ , Naresh
Here also, nothing can be concluded about the person on the left to
Ramakant.
The combination of both the statements is not possible as it contradicts each other.
Hence, Option D is correct.
