Answer C is correct. A transparent Layer 2 switch dynamically learns which ports are associated with MAC addresses by paying attention to the source MAC addresses used in frames that are received on the switch ports. It stores these dynamic entries in its MAC address table. When a frame enters the switch, the switch uses its MAC address table to determine which interface (associated with the destination MAC address) to forward on. Frames that are unknown (not in the table, which include broadcast and multicast destination frames) are forwarded to all other ports that are associated with the same VLAN.
