b. 1, 2, 3, 4
c. 4, 4
d. 4

Answer 1

The cboNumbers combo box will contain the numbers 1, 2, 3, 4 if the Fill() method is called twice.

Step-by-step explanation:

The cboNumbers combo box will contain the numbers 1, 2, 3, 4 if the Fill() method is called twice. The for loop in the method runs from 1 to 4 (excluding 5), and for each iteration, it clears the items in the combo box and adds the current value of i as a new item. Therefore, after two iterations, the combo box will contain the numbers 1, 2, 3, 4.
