  • D The loop throws an error ✔ ✖
Correct Answer: Option A

Explanation

The do-while loop will always execute at least once, even if the condition is false on the first check. This is because the loop body is executed before the condition is checked for the first time. After the first iteration, if the condition is false, the loop will terminate and the program will move on. This behavior is in contrast to a while loop, which checks the condition before the first iteration and may not execute at all if the condition is false initially.
