Question

Which method of waste disposal is more practical to reduce environmental pollution?

• A. Bookish knowledge
• B. Watching disposal related video
• C. Discussing strategies
• D. Organic-Inorganic disposal practices

Hint:

Ask which option is an actual action rather than just reading, watching, or talking about waste.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Environmental education stresses "learning by doing." A method is judged practical when it changes real behaviour, not just when it adds information.

Step 2: Why option D is correct.
Actually separating waste into organic (biodegradable, like food scraps) and inorganic (non-biodegradable, like plastic) and disposing of each correctly is a hands-on habit that directly cuts pollution at the source.

Step 3: Why the other options are wrong.
Bookish knowledge stays theoretical unless it is applied, so it does not by itself reduce waste. Watching a video is passive; it can inform but does not perform any disposal action. Discussing strategies is useful for planning but is still talk, not the practice itself.

Final Answer:
Real organic-inorganic segregation and disposal practice is the practical method. This corresponds to option (D).
