• B. Very poor
• C. Severe
• D. Moderate

Answer 1

The Correct Option is C

The Air Quality Index (AQI) is a measure used to describe the level of air pollution. Different levels of AQI correspond to different levels of health concerns. The typical categories for AQI values in most standards are:

• 0-50: Good
• 51-100: Moderate
• 101-150: Unhealthy for Sensitive Groups
• 151-200: Unhealthy
• 201-300: Very Unhealthy (Very Poor)
• 301-500: Hazardous (Severe)

A value of 470 falls into the "301-500" category, which is classified as "Severe". This indicates that the air quality is very poor and poses a health alert. Everyone may experience more serious health effects.
