An Ethernet network uses ATM as a WAN transport to another Ethernet network on the far end. A frame of 1500 bytes is sent from a host in one network to a host in the far end network. What does the router do with the packet to send it through the ATM network?

A. The router affixes a 53-byte ATM header to the packet and forwards the frame to the ATM switch.

B. The router affixes a 5-byte ATM header to the packet and forwards the frame to the ATM switch.

C. The packet is segmented into 48-byte segments, and a 5-byte header is added to each new segment.

D. The packet is segmented into 5-byte segments, and a 48-byte header is added to each segment.
