Best Answer Explained in Below-:

It seems there might be some confusion in the question regarding the adjective that describes people. The term "pupulous" is not a standard English adjective used to describe people. Instead, the correct answer to the question “What is the adjective of people?” is commonly understood to be **B) popular**.

The adjective "popular" refers to something that is well-liked or admired by many people. For example, you might say that a "popular song" is one that many people enjoy, or that someone is "popular" if they have many friends and are well-received in social settings.

On the other hand, "pupulous" does not appear in standard English vocabulary as an adjective describing people or any specific quality associated with them, hence it would be misleading to consider it correct.

Thus, among the provided options, "popular" (B) is the appropriate adjective related to people, as it encapsulates the essence of being liked or well-regarded by others.
