Option A is inserting the "parakeet" at the 5th position, assuming the list starts at position 0. This would not be the last slot and would cause the "parakeet" to be in the middle of the list.

Option B is inserting the "parakeet" at the first position, which wouldn't add it to the end of the list as requested.

Option C is using the add method that will add the "parakeet" to the end of the list, which is what is requested.

Option D is not a valid method for the ListBox control in VB.NET, so it is not a viable option.
