Which of the following terms means discrete or distinct from one another?

The term "separate" accurately describes something that is discrete or distinct from one another. When we refer to items, entities, or concepts as separate, we emphasize that they are not fused, connected, or part of a larger whole. Instead, they exist independently of one another, highlighting their individuality.

In contrast, "unified" suggests that elements are brought together to form a single entity, which is contrary to the idea of being discrete. "Relative" implies a relationship or comparison between items, indicating that they may not be distinct and may depend on one another for meaning. Lastly, "connected" denotes a linkage or relationship that ties items together, further opposing the notion of being separate. Therefore, the choice "separate" directly aligns with the definition of being distinct or discrete from others.
