The code is missing an initial value for the intCounter variable, which is preventing the loop from executing properly. Adding intCounter = 1 before the Do statement will initialize the variable and allow the loop to execute four times. Option A will cause the loop to execute five times, which is not what the prompt is asking for. Option B is not a valid syntax for a do-while loop. Option D initializes intCounter to 0, but the loop will only execute three times as intCounter will increment from 0 to 1, then 1 to 2, etc.
