Which sentence is correctly punctuated?

• A. We need to buy; bread milk and eggs.
• B. We need to buy bread, milk, and eggs.
• C. We need to buy bread milk, and eggs.
• D. We need to buy bread, milk and eggs.

Answer: (B)

When listing three or more items, use commas to separate each item and often include a final comma before the conjunction to join the last item. The sentence with bread, milk, and eggs does exactly that: it clearly separates each item and uses the final comma before "and eggs," which helps avoid any ambiguity about the items being listed.

Using a semicolon is not appropriate here because there aren’t two complete independent clauses or a more complex list that requires a semicolon. The version without the final comma—bread, milk and eggs—lollows a style that omits the serial comma; while some guides tolerate it, many tests expect the final comma for clarity. The version with bread milk, and eggs mispunctuates the list by failing to properly separate the first two items, making the list harder to read.
