_ Man is the only creature that is endowed with the power of speech.

Explanation

"Man is the only creature that is endowed with the power of speech."Here's why:- No article is needed before "Man" because it refers to humanity as a whole, or the species, rather than a specific individual.- The sentence is making a general statement about the human species, and the lack of an article emphasizes the broad scope of the statement.In this context, "Man" is used to represent the entire human species, making D) no article the correct answer.
