CCNA practice test question.

in CCNA & CCENT
Hello,
I've been trying to refresh some CCNA knowledge. I found a practice test online and I'm dubious about the answer it says it should be. Could someone explain why the Answer is B. Thanks.

Once the reply back is received, the switch can then add that MAC to the appropriate port.
The question itself looks like they either have typos in the mac address table or the packet being sent.
Its E. and its a rather simple process in how a switch works. If the switch receives a frame with a destination address it does not have in its CAM table, it floods the frame out all ports except the port it was received. so E.
