The correct answer is: D. no article
The word "cinema" is a general term for a place where films are shown. It is not a specific place, so it does not need an article.
The other options are incorrect because they are all articles. An article is a word that is used to modify a noun. In this case, the noun is "cinema." The articles "a" and "an" are used before singular nouns that begin with a consonant sound. The article "the" is used before singular nouns that are specific or unique.
In the sentence "I haven't been to cinema in ages," the noun "cinema" is not specific or unique. It is simply a general reference to a place where films are shown. Therefore, it does not need an article.
