Which sentence correctly uses a colon to introduce a list?

• A. We need the following items: notebook, pencil, and ruler.
• B. We need the following items notebook, pencil, and ruler.
• C. We need the following: items notebook, pencil, and ruler.
• D. We need the following items; notebook, pencil, and ruler.

Answer: (A)

Introducing a list with a colon works when the preceding part is a complete thought. In this sentence, “We need the following items” can stand alone, so a colon is used to point to what comes next: notebook, pencil, and ruler. The comma before “and” clarifies that there are three items (the Oxford comma). The other options fail because they either omit the colon, place punctuation in the wrong spot, or use a semicolon, which isn’t the marks used to introduce a simple list.
