The correct answer is: I, II, and III are all used in selecting agricultural extension teaching methods. When selecting agricultural extension teaching methods, the time available for the program, the number of farmers involved, and the agricultural needs of the farmers are all important criteria. For example, if there is limited time available for the program, methods that are quick and easy to implement, such as demonstrations or group discussions, may be preferred. If a large number of farmers are involved, methods that can be scaled up easily, such as radio broadcasts or video presentations, may be preferred. And if the agricultural needs of the farmers are diverse, methods that can be tailored to specific needs, such as individual counseling or farm visits, may be preferred. Therefore, all three criteria are important in selecting the most effective agricultural extension teaching methods.
