E, 0
The only positive factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
Next, remove the odd numbers of that list to get 2, 4, 6, 8, 12, 16, 24, and 48.
No factors fit this description since 24 cannot be larger than itself, and 48 cannot be smaller than itself. Therefore, the answer is zero.
Happy to help, have a great day! :)
