Show answer & explanation

Correct answer: B

Answer: +5 volts supply only

Explanation: The numeral '5' in the microprocessor name indicates the required supply voltage. The 8085 was designed to operate from a single +5 V power supply, unlike some earlier processors that needed multiple supply rails.

  • The 8085 uses a single +5 V supply.

  • It does not require a negative (–5 V) supply.

  • The '5' does not refer to clock frequency or speed.
