Which of the given towns in Kerala meet the clean air benchmark of the CPCB?Select one:a.Malappuramb.Kozhikodec.Kannurd.Kottayam

To determine which of the given towns in Kerala meets the clean air benchmark of the Central Pollution Control Board (CPCB), we would typically need to refer to the latest air quality monitoring data published by the CPCB or related environmental agencies. However, I can provide some context:

1. Research CPCB Standards: The clean air benchmark set by the CPCB involves specific limits for various air pollutants, including PM10, PM2.5, nitrogen dioxide (NO2), sulfur dioxide (SO2), and others.

2. Review Air Quality Data: The air quality index (AQI) and specific pollutant concentrations for the towns in question (Malappuram, Kozhikode, Kannur, Kottayam) would need to be reviewed.

3. Determine Compliance: Compare the air quality data of each town against the CPCB benchmarks to find out which town meets the clean air standards.

Without current and specific air quality data, I cannot conclusively answer which town meets the clean air benchmark. Typically, towns may vary year by year based on industrial activities, traffic, and seasonal variations.

Recommendation: You might want to check the most recent air quality reports from the CPCB or local environmental boards for accurate and updated information. If you need specific data on air quality for these towns, please refer to official environmental reports or databases.
