The correct answer is C. EEPROM.
PROM (Programmable Read-Only Memory) is a type of ROM that can be programmed once using special equipment.
RAM (Random Access Memory) is a type of memory that can be read and written to. It is volatile, which means that it loses its contents when the power is turned off.
EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of ROM that can be erased and programmed electrically. It is non-volatile, which means that it retains its contents when the power is turned off.
Cache Memory is a type of memory that is used to store data that is frequently accessed. It is faster than RAM, but it is also more expensive.
EEPROM is the most advanced form of ROM because it is non-volatile and can be erased and programmed electrically. This makes it ideal for storing data that needs to be retained even when the power is turned off, such as firmware or system settings.
