Which term indicates having great diversity or variety?

The term that indicates having great diversity or variety is "versatile." This word is often used to describe something or someone that can adapt to many different functions or activities, signifying a range of capabilities or styles. When we say something is versatile, it implies that it can change or be utilized in various forms, showcasing diversity in its applications.

The other terms do not convey the same meaning of diversity. "Impassive" refers to a lack of emotion or response, while "gregarious" describes a preference for socializing and being in groups. "Incontrovertible" means something that is undeniable or cannot be disputed, which is unrelated to the concept of variety. Therefore, "versatile" is the term that best aligns with the idea of great diversity or variety.
