- B(i) and (ii)
- C(ii) and (iii)
- D(i), (ii) and (iii)
Solution
Concept
Rule 5A of the Noise Rules restricts horns, construction equipment and crackers in specific zones and times.
Step-by-step solution
1. (i): No horn in silence zones or at night in residential areas, except in a public emergency. This is correct. 2. (ii): The rule bans construction equipment at night in residential areas and silence zones, not in industrial areas. This is wrong. 3. (iii): The rule bans sound-emitting crackers in silence zones and at night (10 pm to 6 am), not in all residential areas at all times. This is wrong. 4. So only (i) is correct.
Explanation
Only statement (i) matches the rule. Construction equipment is restricted at night in residential areas and silence zones, not industrial areas. Crackers are restricted in silence zones and at night, not in all residential areas.
Why the other options are wrong
B, C and D include (ii) or (iii), and both of these are wrongly stated.
Shortcut
Look for changed words such as 'industrial' in place of 'residential'.
Common mistake
Not noticing that the zone or time in the statement has been changed.
Correct answer: A) Only (i)
