correct answer is: option d (SRAM)
Explanation: Volatile memory requires power to maintain the stored information; it loses its data when power is removed. SRAM (Static Random Access Memory) is a type of volatile memory. EPROM and EEPROM are non-volatile memories. DVD is a storage medium, which also is non volatile.

• Option a: EPROM (Erasable Programmable Read-Only Memory) is a type of non-volatile memory, meaning it retains its data even when power is turned off.
• Option b: EEPROM (Electrically Erasable Programmable Read-Only Memory) is also a type of non-volatile memory. It can be electrically erased and reprogrammed.
• Option c: DVD (Digital Versatile Disc) is an optical storage medium and thus, non-volatile. It retains data without power.
• Option d: SRAM (Static Random Access Memory) is a form of volatile memory that uses latching circuitry to store each bit. It requires constant power to maintain data.
