Final Answer :
A
Explanation :
The central processing unit (CPU) is responsible for processing and executing instructions given to it by a program. It examines the inputs, makes decisions based on the program, and sets the outputs accordingly. This is the CPU's primary function, and it is what makes it so critical to computer processing. Choices B, C, and D are incorrect because they do not accurately describe the CPU's role in the computer system.
