Step-by-step explanation:
The correct answer is a) Cache.
A cache refers to a hidden collection or store of valuable items. In this case, the robber led detectives to a hidden stash of stolen gems in the basement. This term is commonly used in the context of crime or treasure hunting. It is important to note that while horde, collection, and stockpile can also refer to a large quantity of items, they do not necessarily imply secrecy or hiddenness like cache does.
'Horde' tends to be used to describe a large group of people or animals, or sometimes an amassed collection (but often with a slightly different connotation). 'Collection' is a general term that could be used but does not convey the secretive aspect associated with the hiding of stolen gems. 'Stockpile' suggests a large reserve of items and is commonly associated with commodities or resources rather than specifically stolen goods.
