Tomorrow will be . . . . . . . . hot day. A. a B. an C. the D. no article

a
an
the
no article

The correct answer is D. no article.

The word “hot” is an adjective that describes the noun “day”. Adjectives do not usually take articles.

In this case, the noun “day” is not specific. It is not referring to a particular day, but to any day that is hot. Therefore, we do not need to use an article.

If we were to use an article, it would change the meaning of the sentence. For example, if we said “Tomorrow will be a hot day”, we would be saying that tomorrow is a particular day that is hot. This is not what we mean. We mean that tomorrow will be any day that is hot.

Therefore, the correct answer is D. no article.
