What does "copious" refer to?

The term "copious" refers to something that is large in number or quantity. It often describes an abundance of something, such as copious notes taken during a lecture or copious rainfall in a particular season. This word implies a generous or plentiful supply, emphasizing the idea of excess rather than limitation. In contrast, the other options suggest scarcity, minimalism, or infrequency, which do not align with the definition of "copious." Therefore, the chosen answer accurately captures the essence of the word as it conveys the notion of abundance.
