Assertion :Some farmers feel that lightning helps produce better crop. Reason: Lighting forms No which is converted to $N O_{2}, H N O_{2}$ and $H N O_{3}$ under atomospheric condition. Thus, $N O_{3}^{-}$ is a source of nutrients (fertilisers) to the plant. Thus there are chances of better crops when lightning occurs.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Reaction:
$N_{2} + O_{2} l i g h t e n i n g - ------- \to 2 N O$
$2 N O + O_{2} ⟶ 2 N O_{2}$
$2 N O_{2} + H_{2} O ⟶ H N O_{2} + H N O_{3}$
So, lighting forms NO which is converted to $N O_{2}, H N O_{2}$ and $H N O_{3}$ under atomospheric condition. Thus, $N O_{3}^{-}$ is a source of nutrients (fertilisers) to the plant. Thus there are chances of better crops when lightning occurs.
