Angela has three brothers: Mark, Adam, and Ryan.

That's the one to go with.

N.B. This is called the syntactical-descriptive function of the colon: it "introduces a description—in particular, makes explicit the elements of a set" (Wikipedia)

The example with no punctuation is horrible by the way. :D – Alenanno Apr 13 '11 at 17:19
The comma before the and really bothers me :| – mplungjan Apr 13 '11 at 17:21
@mplungian: That's another issue. But while the "Oxford comma" may bother you, it's at least a negotiable stylistic point. – Robusto Apr 13 '11 at 17:25
I have it on good authority that the "Oxford comma" didn't even go to college. – The Raven Apr 13 '11 at 17:50
Robusto's answer is correct (of course), but just to add another possibility: you could use a dash, and write Angela has three brothers—Mark, Adam and Ryan. – psmears Apr 13 '11 at 18:10

Angela has three brothers: Mark, Adam, and Ryan.

Welcome to EL&U. Please edit your answer to explain why it is right and to provide at least one reliable citation. Thanks. – MετάEd Jan 29 '13 at 18:06

In a series of three or more terms with a single conjunction, use a comma after each term except the last. With only a few exceptions, the serial comma clarifies any ambiguity when the meaning is not as simple as the example above. Clarity ought to be the objective in writing!
