• B. Along roads
• C. Along canals and other water bodies
• D. On the sloped

Answer 1

The correct option is B Along roads

Green Muffler is a technique of reducing noise pollution by planting 4-6 rows around the populated areas or noisy places like along roadsides, industrial areas, societies near highways, etc. so that dense trees reduce noise pollution as they filter out the noise and obstruct it reaching the citizens. A muffler (silencer in British English) is a device for decreasing the amount of noise emitted by the exhaust of an internal combustion engine.

So the correct answer is 'Along roads'.
