Show answer & explanation
Correct answer: A
The instruction cycle consists of Fetch, Decode, and Execute phases. During the Decode phase, the control unit interprets the binary instruction to identify the specific operation and activates the necessary hardware circuitry accordingly. This distinguishes it from Fetch, which retrieves data, or Execute, which performs the action.
