Assertion (A) is correct: Extension agents, who educate farmers or communities, achieve better outcomes by using a mix of teaching methods (e.g., demonstrations, lectures, workshops, and visual aids) rather than relying solely on one method. This approach accommodates diverse learning preferences and enhances comprehension. Reason (R) is also correct and accurately explains (A): Presenting information through multiple channels (e.g., auditory, visual, hands-on) caters to different learning styles, such as visual, auditory, or kinesthetic, and reinforces understanding, leading to faster and more effective learning. Thus, option (1) is correct, as both statements are true, and (R) directly supports (A).
