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.
