I've got this! The key is to use the concentration formula: C1V1 = C2V2. Since we know the concentration is 25%, we can plug that in and solve for the volume.

Ah, I've seen this type of question before. When a switch receives a frame with unknown source and destination MAC addresses, it will typically save the source address in its MAC table and then flood the frame out to all ports except the incoming port. I'm pretty confident that option C is the correct answer here.
