Concept:The computer processor is internally built from the Control Unit and the Arithmetic Logic Unit (ALU).Explanation:The processor is the brain of the computer. It does not include memory or storage inside itself. The processor has two essential internal parts. The Control Unit manages and directs all operations of the processor. It fetches instructions and controls the flow of data. The Arithmetic Logic Unit performs all arithmetic calculations and logical comparisons. Together, these two parts form the central processing unit. Main memory and storage are separate hardware components connected to the processor. The operating system and application software are not physical parts of the processor. Therefore, the only correct pair of processor parts is the Control Unit and the ALU.Answer:B. Control unit and ALU
