Hint:

To classify visual aids:
- Projected = Needs a screen/projector (Powerpoint)
- 3D = Has depth (Puppets)
- 2D = Flat (Flip charts)

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Audio-visual aids are instructional materials used by extension workers and teachers to make communication more engaging, understandable, and memorable.
These aids are classified based on their physical dimensions and projection requirements.

Step 2: Detailed Explanation:
Let us match each type of audio-visual aid with its correct example:
- 2D (Two-Dimensional) Aids (A): These are flat visual aids that have only length and width.
Flip charts (III), which consist of a series of large paper sheets bound together at the top on a stand, are a classic example of a 2D non-projected visual aid.
- 3D (Three-Dimensional) Aids (B): These are visual aids that have length, width, and depth, offering a realistic representation.
Puppets (I), models, and specimens are examples of 3D non-projected aids.
- Projected Aids (C): These are visual materials that require a projection system and light source to project the image onto a screen.
Powerpoint presentations (II) and slides are common examples of projected aids.
- Non-Projected Aids (D): These are materials that do not require projection and can be viewed directly.
Exhibits (V), posters, and bulletin boards are examples of non-projected displays used to share information.
This matching corresponds to the sequence: A-III, B-I, C-II, and D-V.

Step 3: Final Answer:
The correct matching is represented by option (A).
