In which method of on-the-job training, the trainee is kept under the guidance of a master worker?

Option 1 -> Vestibule training is conducted in a separate training area that replicates the actual work environment, not under direct guidance of a master worker on the actual job.

Option 2 -> Apprenticeship involves a trainee working directly under the supervision and guidance of an experienced master worker or craftsperson to learn specific skills and trade over a period of time.

Option 3 -> Job Rotation involves moving trainees across different departments or jobs to provide diverse experience, not continuous guidance under one master worker.

Option 4 -> Simulation uses artificial environments and models to replicate real work situations for training purposes, not actual guidance from a master worker.

Hence, Option 2: Apprenticeship -> In this on-the-job training method, the trainee works under the direct guidance and supervision of a master worker or skilled craftsperson who mentors them through hands-on experience, teaching them the trade or skill systematically -> correct
