Answer 1

The Correct Option is C

Concept: Noise pollution control aims to reduce excessive and harmful sound levels in the environment. Common methods of noise control include:
• Controlling vehicle and industrial noise
• Proper urban and city planning
• Public awareness and education
• Use of silencers and sound barriers Unregulated construction activities increase noise pollution rather than control it.

Step 1: Analyze option A.
Reducing and controlling vehicle noise is an important method of noise control.
Hence, option A is a correct method.

Step 2: Analyze option B.
Careful planning of cities helps separate residential, industrial, and commercial zones, thereby reducing noise pollution.
Hence, option B is a correct method.

Step 3: Analyze option C.
Allowing construction activities in all parts of a town increases environmental noise and disturbs residential areas.
Thus, it is not a method of noise control.
Hence, option C is correct for the “except” question.

Step 4: Analyze option D.
Public awareness and education help people understand the harmful effects of noise pollution and encourage preventive measures.
Hence, option D is a correct method. Therefore, the correct answer is: \[ \boxed{(C)\ \text{Allow construction activities in all parts of a town}} \]
