Kiran is . . . . . . . . best student in the class. A. a B. an C. the D. no article

The correct answer is: D. no article

The word “best” is an adjective that modifies the noun “student.” Adjectives do not usually take articles.

In this case, we are not comparing Kiran to any other students. We are simply stating that Kiran is the best student in the class. Therefore, we do not need to use an article.

If we were comparing Kiran to other students, we would use an article. For example, we could say:

• Kiran is the best student in the class. (This means that Kiran is better than all of the other students in the class.)
• Kiran is a good student. (This means that Kiran is better than some of the other students in the class, but not necessarily all of them.)

I hope this helps! Let me know if you have any other questions.
