a. the loop control variable must change
b. the loop control variable must be input from the keyboard
c. the loop control variable must be true
d. the loop control variable must change inside the loop

Answer 1

In order for a loop to stop, the loop control variable must change.

Step-by-step explanation:

In order for a loop to stop, the loop control variable must satisfy a certain condition. This condition can be set in different ways depending on the programming language used. However, generally speaking, the loop control variable must change in order for the loop to stop.

For example, in a for loop in Python, the loop control variable is initialized with a starting value and it increments or decrements by a certain amount after each iteration. The loop continues to run until the loop control variable no longer satisfies the specified condition.

So, option A is the correct answer: the loop control variable must change for the loop to stop.
