In order to add an item to the ArrayBag, we need to increase the size attribute of the object. Option C increments the size attribute, whereas Option A tries to increment the list itself, which is not correct syntax. Option B tries to reassign the self reference, which is not necessary or desirable in this case. Option D tries to reassign the length of the items attribute to the len variable of self, which is not the correct syntax or logic. Thus, the best choice is C.
