• B. If the data in statement II alone are sufficient to answer the question, while the data in statement I all are not sufficient to answer the question;
• C. If the data in either statement I alone are statement II alone are not sufficient to answer the question;
• D. If the data even in both statements I and II together are not sufficient to answer the question;
• E. If the data in both statements I and II together are necessary to answer the question.

Answer 1

The correct option is A If the data in statement I alone are sufficient to answer the question, while the data in statement II alone not sufficient to answer the question;

From Statement 1: He has 17th rank from top among all students, and 12th rank among boys.

Removing boys, 17 - 12 = 5 girls are taller than Samir.

From Statement 2: 29 - 18 = 11 girls are shorter than Samir. But it not known how many girls are there in the class.

Hence, this statement alone is not sufficient to answer the question.

Thus, option A is correct.
