Correct option is A
·
Control: The control unit (CU) is a critical component of the CPU (Central Processing Unit). It directs the operation of the processor by telling the computer's memory, ALU (Arithmetic Logic Unit), and I/O devices how to respond to the instructions that have been sent to the processor. The control unit manages and coordinates all the activities of the CPU, ensuring that the data flows correctly between the CPU and other components.
· Memory: The memory unit is responsible for storing data and instructions that are used by the CPU, but it does not control or direct operations.
· Arithmetic Logic: The Arithmetic Logic Unit (ALU) performs arithmetic and logical operations, such as addition, subtraction, and comparison, but it does not control the operations of the CPU.
· Data: Data is the raw information processed by the CPU, not a unit or component of the CPU that controls operations.
