The correct answer is D. no article.
Kobe Bryant is a basketball player. He is not a specific basketball player, but rather a general basketball player. Therefore, we do not need to use an article.
An article is a word that comes before a noun to indicate whether the noun is specific or general. The definite article “the” is used to refer to a specific noun, while the indefinite articles “a” and “an” are used to refer to a general noun.
In this case, Kobe Bryant is not a specific basketball player, but rather a general basketball player. Therefore, we do not need to use an article.
