Vedclass · Answer

(A) The Assertion is correct because the emission of sulfur dioxide $(SO_2)$ and nitrogen oxides $(NO_x)$ from industrial activities and vehicles reacts with atmospheric water vapor to form sulfuric acid and nitric acid,leading to acid rain.The Reason is also correct because acid rain lowers the $pH$ of the soil and water bodies,which directly damages the foliage (leaves) and growing points (meristematic tissues) of plants,thereby inhibiting their growth and development.Since the damage to plants is a direct consequence of the environmental impact caused by acid rain,the Reason correctly explains the Assertion.

$A$: High concentration of atmospheric $SO_2$ and $NO_x$ causes acid rain.
$R$: It causes damage to foliage and growing points of plants.
