. . . . . . . . school that Ram goes to is old. A. a B. an C. the D. no article

The correct answer is: D. no article

The article “a” or “an” is used before singular nouns that refer to something that is not specific. In this case, the school that Ram goes to is not specific, so we do not use an article.

The article “the” is used before singular nouns that refer to something that is specific. In this case, the school that Ram goes to is not specific, so we do not use “the”.

No article is used before plural nouns and uncountable nouns. In this case, the noun “school” is singular, so we do not use an article.
