Quizplus · Accepted Answer

The program in choice B is self-terminating because it decrements the value of X in the loop condition and will eventually cause the loop to terminate when X reaches 0.

Option A is not self-terminating because there is no decrement of X, and it will create an infinite loop.
 
Option C is not self-terminating because X is decremented inside the loop, but there is no condition to terminate the loop, which also creates an infinite loop.
