In terms of storage, which word implies a hidden collection of items?

The word "cache" refers specifically to a hidden collection of items, often used in contexts involving technology, such as storing data temporarily in a computer's memory, or in general use when referring to supplies or valuables that are hidden away for future use. This term conveys the idea of something being stored discreetly, often in a way that is not immediately visible or obvious to others.

The other options do not carry this meaning. "Clad" relates to being covered or dressed, and does not suggest anything about storage or hidden items. "Clarify" means to make something clear or understandable, which is the opposite of implying anything hidden. "Bountiful" describes a large quantity of something, typically in a positive context, but does not pertain to the concept of hiding or storing items. Therefore, "cache" stands out as the term that accurately embodies the notion of a concealed collection.
