D. if the data in both statements I and II together are necessary to answer the question.

Answer

D

Explanation

From statement I:
Sangita.s rank from the left end `to` 3rd Sangita `to` 3rd to the left of Hasina. So, Hasina.s rank from the left end `to` (3+3) or 6th.
From statement II :
Rakesh.s rank from the right end `to` 5th Rakesh `rArr` 3rd to the right of Hasina. So, Hasina.s rank from the right end `to` (5+3) or 8th.
From I & II, we get
Total number of children = (6 + 8) - 1 = 13
Therefore, the data in both the statements I and II together are necessary to answer the given question.
