The correct answer is D. no article.

The sentence "She does not eat chicken" is a negative sentence. In negative sentences, we do not use articles unless the noun is specific. In this case, the noun "chicken" is not specific, so we do not use an article.

Here are some examples of sentences where we would use an article with "chicken":

  • She eats a chicken every day.
  • She ate the chicken that I cooked.
  • She is a chicken farmer.

In these sentences, the noun "chicken" is specific. In the first sentence, the speaker eats a particular chicken every day. In the second sentence, the speaker ate a particular chicken that the listener cooked. In the third sentence, the speaker is a chicken farmer, which means that she raises chickens.

In the sentence "She does not eat chicken," the noun "chicken" is not specific. The speaker is not talking about a particular chicken, or all chickens in general. She is simply saying that she does not eat chicken. Therefore, we do not use an article.
