Options

A. if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question
B. if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
C. if the data either in statement I alone or in statement Il 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 statement I:
Abhijit.s rank from the top `to` 10th So, Sunetra.s rank from the top `to` (10+7) or, 17th So, statement I is sufficient. From statement II :
Sudhakar.s rank from the bottom `to` 23rd So, Sunetra.s rank from the bottom `to` (23+6) or 29th
So, Sunetra.s rank from the top = (45-29) + 1 = 17th
So, statement II is sufficient.
Therefore, the data either in statement I alone or in statement II alone are sufficient to answer the given question
