Speed is irrelevant in most cases. lol
I agree. Speed is usually the most irrelevant factor for me. Usually, a low fsb was just the ticket for a great overclock, so I really didn't care what the stock speed of the cpu was, as long as it was slow enough to make the jump up to the next fsb and still be stable.
but OP, seriously? You need help with that homework question? C'mon man, did somebody twist your arm to take introductory computer class? That's a pretty easy question. Almost anyone interested in computers should have a decent idea as to the correct answer.
