Which unit first receives data entered by a user in a computer system?

Answer and explanation

Correct answer: Input unit

The governing concept is the input–process–output cycle. The input unit receives raw data and instructions from the user through devices such as a keyboard, mouse, scanner, or microphone. It is therefore the first receiving unit, making option C correct. The processing unit works on the data after entry, storage preserves it, and the output unit presents the processed result to the user.
