I. Mr. Roy has come to the bus stand at 9 A.M.
II. There is a bus at 10 A.M. and possibly another bus even earlier.

• C. If the data either in I or II alone are sufficient to answer the question;
• D. If the data in both the statements together are needed.

Answer 1

The correct option is D If the data in both the statements together are needed.

From both the given statements, we find that Mr. Roy reached the bus stand at $9$ AM and a bus is sure to arrive at $10$ AM. So. Mr. Roy has to wait for at the most one hour.

so both statements are needed to answer the question.

option D
