Explanation:

The Air Quality Index (AQI) in India, defined by the CPCB, considers eight major pollutants: $PM_{2.5}$, $PM_{10}$, $NO_2$, $SO_2$, $CO$, $O_3$, $NH_3$, and $Pb$. Carbon dioxide ($CO_2$) is a greenhouse gas contributing to climate change but is not considered a direct air pollutant for AQI purposes, which focuses on pollutants with direct adverse health effects. Option (1) $PM_{10}$, Option (2) Carbon monoxide ($CO$), and Option (3) Lead ($Pb$) are all explicitly included as pollutants in India's AQI due to their direct health impacts.
