Counter-controlled loops are used when we know the number of times a loop should execute in advance. This is achieved by initializing a counter variable before the loop, checking a condition at the beginning of each iteration, and incrementing the counter at the end of each iteration. The loop will execute until the condition becomes false or until the counter reaches a certain value. Sentinel loops are used when we do not know in advance how many times a loop will execute, and infinite loops are loops that execute forever. Therefore, the best choice in this scenario would be a counter-controlled loop.
