[单项选择]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.
