The correct answer is B. 5.
The For loop will iterate from 5 to 1, with a step size of -1. This means that the loop will execute 5 times, with the value of intNum being 5, 4, 3, 2, and 1. The MessageBox.Show method will be called once for each value of intNum.
Option A is incorrect because the loop will only execute 5 times. Option C is incorrect because the loop will only execute 4 times. Option D is incorrect because the loop will only execute 7 times.
