The correct answer is option 2- BDE.
Option A & C are on the job training method.
- Films: They can provide information and explicitly demonstrate skills that are not easily represented by the other techniques. Used in conjunction with conference discussions, it is a very effective method in certain cases.
- Case Study: Taken from actual experiences of organisations, cases represent attempts to describe, as accurately as possible real problems that managers have faced. Trainees study the cases to determine problems, analyse causes, develop alternative solutions, select what they believe to be the best solution, and implement it.
- Class Room Lectures: The lecture or conference approach is well adapted to conveying specific information, rules, procedures or methods. The use of audio-visuals or demonstrations can often make a formal classroom presentation more interesting while increasing retention and offering a vehicle for clarifying more difficult points.
