Choose the correct answer from the options given below:

• A. (A) and (B) only.

Hint:

People remember about 10% of what they read, 20% of what they hear, 30% of what they see, and 50% of what they both hear and see (audio-visual).
This demonstrates why AV aids are highly effective.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Audio-visual (AV) aids are instructional devices that appeal to both the sense of hearing and the sense of sight.
They are used in agricultural extension and teaching to enhance communication, make learning active, and improve retention.

Step 2: Detailed Explanation:
Let us evaluate each statement:
- (A) Audio visual aids improve teaching:
AV aids clarify abstract concepts, sustain interest, and engage multiple senses, making the teaching-learning process more effective.
Therefore, Statement A is correct.
- (B) Audio visual aids increase efforts:
In extension pedagogy, AV aids are used to *reduce* the time and effort required by both the teacher and the learner to convey and understand complex information. They simplify communication rather than increasing effort.
Therefore, Statement B is incorrect.
- (C) Audio visual aids reduce learning:
AV aids enhance comprehension and retention, thereby *increasing* learning outcomes.
Therefore, Statement C is incorrect.
- (D) Audio visual aids distract message:
Properly selected AV aids reinforce and focus the educational message rather than distracting from it.
Therefore, Statement D is incorrect.
Thus, only statement (A) is correct.

Step 3: Final Answer:
The correct option is (B).
