Which loop repeats while the condition remains true?

Which loop repeats while the condition remains true?

• A. Repeat until loop
• B. For loop
• C. Output command
• D. While loop

Answer: (D)

Loops continue based on a condition, and the way that condition is checked determines the type. A while loop checks the condition before each iteration, so it keeps repeating as long as that condition stays true. If the condition becomes false, the loop stops. This matches the idea of repeating while the condition remains true. In contrast, a repeat-until loop runs the body first and then checks the condition, so it keeps looping until the condition becomes true; it doesn’t repeat strictly while the condition is true. A for loop runs a predetermined number of times or over a fixed set of items, not based on a condition that might change during execution. An output command is not a looping structure.
