Step-by-step explanation:
The answer to the question is d. Folder. A folder is a collection of files typically created for organizational purposes on a computer or in a file system. Unlike a single file, which is a document or application that can be opened and modified, a folder is a virtual container within a computer's storage system or on a particular drive, where multiple files and other folders can be stored.
