AP means that it was written by a Associated Press and UPI means that it was written by the United Press International
I think it was a<span> large iceberg that ripped the side of the ship.</span>
The sentence which uses the correct comma usage is B. Suzie, my best friend, is also an amazing athlete.
A. is wrong because there should be a comma after Mr. Morrish. C. is wrong because there should be a comma after state. And D. is wrong because there shouldn't be a comma after told it should be after Bradley.
Hope this helps. :)
