Before we answer this question, it is worthy to note the meaning of CSMA/CD. It stands for carrier-sense multiple access with collision detection which is a media access control method that is used for local area networking (LAN). In here, the transmitting station will detect collision by sensing the transmissions from other stations. Now, from the given choices, some of the characteristics of CSMA/CD are letters A, B, C.

CSMA/CD monitors the media for presence of a data signal. After detecting a collision, the host can resume transmission after a random timer has expired. And a jam signal is used to ensure that all hosts are aware that a collision has occurred. You can learn more about CSMA/CD with a simple google search, or you can visit its Wikipedia page.
