Which sentence uses correct comma usage in a list?

• A. We bought apples, oranges, and bananas.
• B. We bought apples, oranges and bananas.
• C. We bought apples oranges, and bananas.
• D. We bought apples; oranges, and bananas.

Answer: (B)

When you list several items, use punctuation to separate them clearly. In this sentence, apples, oranges and bananas are listed with a comma after the first item and with and joining the last item—without putting a comma before and. That matches the common rule taught for simple lists at this grade level, where the final comma before and is often omitted. The other options either put a comma before and (an Oxford comma) or use punctuation that doesn’t fit a straightforward list, like a semicolon.
