Correct option is C
Micro operations are the operations performed on data stored in registers. These operations are fundamental, low-level instructions that typically involve transferring data between registers, performing arithmetic or logical operations, or manipulating data within the CPU. Each micro-operation corresponds to a small, atomic action, which is a basic part of the execution of an instruction within the CPU.
Micro operations are critical in the functioning of a processor, as they form the steps that make up complex machine instructions. They operate at a level below the machine language instructions and are used in the implementation of these instructions by the control unit of the CPU.
Thus, the correct answer is (c) Micro operations.
