How are incoming frames handled by a Switch?

The Switch broadcasts the contents of the frames to every device on the Network.
The Frames are sent only to the interface associated with the Destination MAC Address
The Frames are received by every NIC, but only the NIC with the matching MAC Address processes the Frame.
The Switch forwards the Frames to every device on the Network.
