Which sentence correctly uses a comma in a list?

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

Answer: (A)

When you list several items, each item needs to be clearly separated with commas. For three or more items, you put a comma after each item except the last, and you use a coordinating conjunction (like and) before that final item. This final comma before the and is often called the serial comma. It helps the list read clearly as three distinct things: apples, bananas, and oranges. That makes the sentence with apples, bananas, and oranges the correct choice, because every item is clearly separated and no item blends into the next. The other versions either skip a needed comma, misplace a comma, or put punctuation where it doesn’t fit, which can make the list harder to read or change how the items are understood.
