C. if the data either in statement I alone or in statement II alone are sufficient to answer the question,
D. if the data given in both statements I and II together are not sufficient to answer the question,

Answer

C

Explanation

From I, we conclude that in a class of 47 students, Gaurav ranks `18^(th)` from the top and hence `30^(th)` from the last.
From II, we conclude that there are 9 students above and 37 students below Jatin in rank. Thus, there are (9 +1 + 37) = 47 students in the class. So, Gaurav who ranks `18^(th)` from the top, is `30^(th)` from the last.
