The Correct options are BD. I'm gonna explain: A -> Wrong, because enhanced for cannot read collections in reverse and alternately, it loops through each element and only in an ascending way. B -> Correct, with standard for you can go through elements of a collection in ascending, descending and alternating ways. C -> Wrong, you can loop backwards through an i-- in the third parameter of your for with the correct condition and you can also access collections alternately instead of putting "i++" in the third parameter of the standard for you, you can put the expression "i = i + 2" or any other number you want in place of 2. D -> Correct, an enhanced for processes all elements of an array in input form. E -> Wrong, you can do it alternately with a standard for as I explained in alternative C.
