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

Answer

D

Explanation

From statement I:
D `to` Immediate right of E.
B `to` Immediate left of E.
So, the arrangement in the row is as follows:
`B" "E" "D`
But there is no information regarding A and C. So, statements I alone is not sufficient.
From statement II :
B `to` Extreme left of the row.
But there is no information regarding A, C, D and E. So, statements II alone is not sufficient.
Form I & II, we get

So, D `to` third child.
So, Middle child `to` third child `to` D.
Therefore, the data in both statements I and II together are necessary to answer the given question.
