Explanation:

The question asks for the term that quantifies the amount of data a storage medium can store. Option (a) 'access' refers to the process or speed of retrieving data from storage, not the quantity it can hold. Option (b) 'capacity' is the precise term used to describe the total amount of data that a storage device or medium (like a hard drive, USB drive, or RAM) can store. This is the correct answer. Option (c) 'memory' is a type of storage (e.g., RAM, ROM), but 'capacity' is the measure of how much data that memory can hold. 'Memory' itself is not the indicator of 'how much data it can hold' in the way 'capacity' is. Option (d) 'storage' is a general term for where data is kept, but like 'memory', it doesn't specifically indicate the *amount* of data. Option (e) 'none of these' is incorrect as option (b) is the appropriate term.
