The correct answer is D. no article.
The article “a” or “an” is used before a singular noun that is not specific. In this case, the noun “doctor” is not specific because it does not refer to a particular doctor. The doctor who looked after Thomas’s uncle could be any doctor. Therefore, we do not use an article.
The article “the” is used before a singular noun that is specific. In this case, the noun “doctor” would be specific if it referred to a particular doctor, such as the doctor who lives on the corner or the doctor who is Thomas’s uncle’s favorite. However, in this case, the noun “doctor” is not specific, so we do not use the article “the.”
