Assertion (A) : The output unit of a computer system supplies results to the outside world.
Reason (R) : The output unit converts the coded results produced by the computer into a human-readable form.

  • A.Both (A) and (R) are true, and (R) is the correct explanation of (A).
  • B.Both (A) and (R) are true, but (R) is not the correct explanation of (A).
  • C.(A) is true, but (R) is false.
  • D.(A) is false, but (R) is true.

Answer: A

The answer is Both (A) and (R) are true, and (R) is the correct explanation of (A).

The output unit, through devices such as monitors and printers, supplies the results of processing to the user. It can do so only because it converts the computer's internal binary-coded results into a form people can read, such as text, images or sound.

That conversion is exactly how the output unit supplies results to the outside world, so the Reason explains the Assertion, which rules out the option saying it does not.
