Italy is . . . . . . . . European country. A. a B. an C. the D. no article

The correct answer is D. no article.

The word “Italy” is a proper noun, which means it refers to a specific place. Proper nouns are not preceded by articles.

The other options are incorrect because they are all articles. Articles are words that are used to modify nouns. They can be used to indicate whether the noun is specific or general, and they can also be used to indicate whether the noun is singular or plural.

In this case, the noun “Italy” is specific and singular. Therefore, no article is needed.
