Answer 2

The fastest memory is c) cache memory.

Explanation:  

• Cache memory is very fast memory in-built into the computer system’s “central processing unit” (CPU). The computer uses cache for storing CPU instructions with contrast to RAM used to store less frequently accessed data.
• A Hard disk is a magnetic data storage unit device that keeps storing and retrieving the digital information.
• The main memory in a computer is called Random Access Memory which is also known as RAM. This is the part of the computer that stores operating system software,
• “Blu-ray Disc, BD or BD-ROM” is an optical disc data storage format.
