Option 3 : (A) and (C) only

Primary storage:

Primary storage is often referred to as “memory” and is classified as either volatile or non-volatile.
It temporarily stores applications and data currently in use.
Volatile memory such as RAM loses data as soon as the device loses power.
- RAM is a volatile memory, which means it does not store data or instructions permanently.
- As soon as you shut down the computer, the RAM loses the data. So, the data remains in the RAM as long as the computer is on and is lost when the computer is turned off.
Primary storage provides fast access to the CPU and allows active programs to deliver optimal performance to the end-user.

Secondary storage devices

It refers to any non-volatile storage device that is internal or external to the computer.
It can be any storage device beyond the primary storage that enables permanent data storage.
A secondary storage device is also known as an auxiliary storage device, backup storage device, tier 2 storage, or external storage.
The secondary memory is accessed indirectly via input/output operations.
Secondary storage is named as such because it doesn't have direct access to the CPU. As a result, it is considerably slower than primary storage
Secondary storage is usually twice as cheap compared to its primary counterpart and can also store significantly more information.
It can be of Two types
- Sequential access:
  - For example, A tape drive is a device that stores computer data on magnetic tape, especially for backup and archiving purposes. Magnetic tape drive
- Direct access:
  - For example Floppy disc

Therefore we conclude that the correct answer is (A) and (C) only
