Adding commas in a series (Oxford comma) prevents ambiguity and clarifies separate items. The correct answer uses commas after each item: 'apples, oranges, and bananas.' Without commas, it could be misread as 'apples oranges' (a type of orange). Proofreading for punctuation precision ensures lists, clauses, and phrases are clearly separated. For example, 'Let's eat, Grandma!' vs. 'Let's eat Grandma!' shows how commas save lives!
