What type of training occurs "on the job"?

On-the-job training involves learning skills and knowledge while actively engaged in the work environment, which is precisely what option B describes. This method typically includes tasks such as observing experienced colleagues, practicing skills under supervision, and receiving immediate feedback on performance. It integrates practical experience with learning, allowing employees to gain hands-on experience and familiarize themselves with the specific tools, technologies, and processes used in their roles.

This method is particularly effective because it allows trainees to learn in real-time, enhancing retention and application of knowledge while also contributing to productivity from day one. In contrast, the other options do not align with the concept of on-the-job training; they involve theoretical or classroom-based approaches, separate locations for training, or online courses that do not provide the immediate practical experience of working in the actual job environment.
