2.【答案】A。
解析：On-the-job approaches support transfer of learning': skills are learned in the actual context in which they will be applied - so application is seamless. The first two options are advantages of off-the-job training: the learners don't have the distraction of other work duties, and errors while learning are less likely to have real consequences. You may have hesitated over the third option, but there is a risk that by learning on the job, people will pick up 'bad habits' and short-cuts - rather than best practice.
