• E. If the data in both statements I and II together are necessary to answer the question.

Answer 1

Answer: (D)

If the data even in both statements I and II together are not sufficient to answer the question;

Through Statement I,

A reached at 7.15 am five minutes before the bell rang.

Nothing can be said about the arrival of B and C by this statement.

Through Statement II,

C reached the school before the bell rang, and B reached before him.

That means B also reached the school before the bell rang.

So, between B and C, this can be said that B reached the school first. But, Nothing can be said about the A as of when it reached school among B and C.

Thus, Option D is correct, that the data even in both Statements I and II together is not sufficient to answer the question.
