He hopes to join . . . . . . . . university soon. A. a B. an C. the D. no article

The correct answer is D. no article.

The word “university” is a countable noun, which means it can be preceded by a number or an article. However, in this case, the speaker is not referring to a specific university, but rather to university in general. Therefore, no article is needed.

Here are some examples of how the word “university” can be used with an article:

• He wants to attend a university.
• He is applying to the University of California, Berkeley.
• He is a graduate of Harvard University.

In these examples, the speaker is referring to a specific university. Therefore, an article is needed.

However, in the original sentence, the speaker is not referring to a specific university. Therefore, no article is needed.
