On a half-duplex Ethernet LAN, two hosts attempt to send data simultaneously,resulting in a collision. Following this collision, what will the hosts do?（）
A
The destination host sends a request to the source for retransmission.
B
The jam signal indicates that the collision has been cleared.
C
The hosts will attempt to resume transmission after a time delay has expired.
D
An electrical pulse indicates that the collision has cleared.
E
The router on the segment will signal that the collision has cleared.
F
The hosts will do nothing, as the higher layers are responsible for data error correction and re-transmission.
