Option c is correct. If a loop does not contain, within itself, a valid way to terminate, it is called a while loop.
A while loop is a control flow statement that enables code to be performed repeatedly based on a specified Boolean condition in the majority of computer programming languages. The while loop can be viewed as an iterative version of the if statement.
When a condition is not satisfied, a "While" loop is used to repeat a certain piece of code an undetermined number of times. For instance, if we want to ask a user for a number between 1 and 10, but we don't know how often they might enter a greater number, we keep asking "while the value is not between 1 and 10."

what is the minimum number of cycles needed to completely execute n instructions on a cpu with a k stage pipeline? justify your formula.
The minimum number of cycles needed to completely execute n instructions on a cpu with a k stage pipeline is k+(n-1).
What is a pipeline?A pipeline is the mechanism by which a RISC processor executes instructions. By fetching the next instruction while other instructions are decoded and executed, a pipeline speeds up execution. Consider the pipeline to be an automobile assembly line, with each stage performing a specific task in the production of the vehicle.
The circuit is divided into k parts by a K stage pipeline. It is K times faster because each stage has the same transistor delay (ideally). (For example, a conveyor belt system in a car factory)
As we have k stage pipeline. For the first instruction we take k cycles and for the next n-1 instructions we take only n-1 cycles. So the total clock cycles will be k+(n-1).
