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.
