Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Avogadro's law of gaseous volumes states that $1 m o l e$ of any gas at NTP occupies $22.4 L$ volume at STP.
STP $⟹$ Same temperature and pressure.
Thus, according to avogrado's law, $1 m o l e$ of $N_{2}$ and $O_{2}$ have same volume at same temperature and pressure.
