The correct answer is B. main storage.
The main storage, also known as primary storage or RAM, is the computer’s short-term memory. It is where the microprocessor stores the instructions and data that it is currently working on. The main storage is much faster than secondary storage, such as hard drives, but it is also much smaller.
The ALU, or arithmetic and logic unit, is the part of the microprocessor that performs arithmetic and logical operations. The logic unit is responsible for making decisions, such as comparing two numbers or checking if a condition is true.
The secondary storage, also known as auxiliary storage or long-term storage, is where the computer stores programs and data that are not currently being used. The secondary storage is much larger than the main storage, but it is also much slower.
E is not the correct answer because the microprocessor can operate on information that is in its main storage.
