- B.
  
  It is lost
- C.
  
  Nothing
- D.
  
  It request the user to save it
Correct Answer
C. Nothing

Explanation
When the computer is turned off, the information stored in ROM (Read-Only Memory) remains unaffected. ROM is a type of non-volatile memory, meaning that it retains its data even when power is lost. Unlike RAM (Random Access Memory) which is volatile and loses its data when the computer is turned off, ROM is designed to store permanent instructions and data that are essential for the computer's basic operations. Therefore, the information stored in ROM remains intact and does not change or get lost when the computer is powered off.

- A.
  
  Use a filtered plug
- B.
  
  Make frequent back ups of the data
