Show answer & explanation
Correct answer: C
Step 1: The control unit is responsible for managing and coordinating all components of the computer system, including the CPU, memory, and input/output devices. This makes statement I correct.
Step 2: The control unit does not perform actual data processing such as arithmetic or logical operations. These tasks are handled by the ALU. Therefore, statement II is also correct.
Step 3: Since both statements I and II are accurate descriptions of the control unit's functions, the correct choice is the one that includes both.
