A. After a collision, the station that detected the collision has first priority to resend the lost data.

B. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.

C. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.

D. The use of hubs to enlarge the size of collision domains is one way to improve the operation of the CSMA/CD access method.
