A safety cue serves an essential role in training by informing clients about potential injury risks. This aspect of training is crucial because it helps clients to be aware of their movements and the proper techniques to use, reducing the likelihood of injury. For instance, a personal trainer might remind a client to keep their knees aligned with their toes during a squat, which can prevent undue strain on the joints.

In contrast, enhancing performance speed, motivating clients, or encouraging nutritional habits are all valuable components of a well-rounded training program but do not directly address safety concerns. Performance speed pertains more to improving the efficiency of exercise execution, which is not the primary goal of a safety cue. Motivation can help push clients during tough workouts, yet it does not provide the necessary protective information needed to mitigate risks. Likewise, post-workout nutrition guidance is important for recovery and overall health but is unrelated to the immediate physical safety of the client during exercise. Therefore, the primary purpose of a safety cue is to ensure that clients are aware of potential injury risks, making option B the correct choice.
