The correct answer is C. ROM.
ROM (Read-Only Memory) is a type of non-volatile memory that stores permanent data and instructions that are used to start a computer. The BIOS (Basic Input/Output System) is a firmware that is stored in ROM. The BIOS initializes the hardware and loads the operating system from the hard drive into RAM.
CPU (Central Processing Unit) is the main processor of a computer. It is responsible for executing instructions and carrying out tasks.
RAM (Random Access Memory) is a type of volatile memory that stores data and instructions that are currently being used by the computer. It is much faster than ROM, but it loses its contents when the computer is turned off.
E. None of the above is not the correct answer.
