The correct option is D All of the above

Processors of all computers, micro, mini or mainframe must have ALU,Primary storage and Control Unit.

There are two primary manufacturers of computer microprocessors. Intel and Advanced Micro Devices (AMD) lead the market in terms of speed and quality. Intel's desktop CPUs include Celeron, Pentium and Core. AMD's desktop processors include Sempron, Athlon and Phenom.

Intel introduced the 8008 processor on April 1, 1972. Intel's improved microprocessor chip was introduced on April 1, 1974; the 8080 became a standard in the computer industry. Intel introduced the 8085 processor in March 1976. The Intel 8086 was introduced on June 8, 1976.

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs.

In this case, primary storage typically refers to random access memory (RAM), while secondary storage refers to the computer's internal hard drive. RAM, commonly called "memory," is considered primary storage, since it stores data that is directly accessible by the computer's CPU.

The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to the instructions that have been sent to the processor.
