In C#, index values of elements start from 0, so to remove the sixth item from the lstTrees control, we need to use the RemoveAt method with an index value of 5. Therefore, the correct choice is option C, lstTrees.Items.RemoveAt(5). Option A (lstTrees.Items.Remove(5)) removes the element with value 5 from the list, not the sixth element. Option B (lstTrees.Items.Remove(6)) removes the element with value 6 from the list, which may not be the sixth element. Option D (lstTrees.Items.RemoveAt(6)) removes the seventh element from the list, which is not what we intend to do.
