• B. Cache memory
• C. ROM
• D. USB Flash drive

Answer 1

Answer:

D. USB Flash drive

• Solid State Drive (SSD) does not belong to the class of primary memory.

• It is a type of secondary memory or storage.

• Primary Memory (also known as main memory) is directly accessible by the computer's CPU.

• It's used for temporarily holding data and program instructions that the CPU is actively using.

• It is typically faster but has a lower storage capacity and is more expensive per gigabyte than secondary memory.
