Answer

Brief Explanations:

In English writing, when listing items, a comma is added before the "and" before the last item. For example, "apples, bananas, and oranges". Ending a list with a colon is incorrect for separating list - items. Separating items with colons is also wrong. Adding a comma after "and" is not the correct practice.

Answer:

add a comma before the "and" before the last item.
