When a collision occurs in CSMA/CD, a jamming signal is sent immediately to both sending nodes, and then they wait for a random period of time before trying to send their data again. This is known as the backoff algorithm, which helps to reduce the likelihood of another collision occurring. The random period of time is important because if the nodes waited for a fixed period of time, they might end up colliding again if they try to send their data at the same time. By waiting for a random interval, the probability of another collision is reduced. Therefore, choice D is the best answer.
