Solution

The correct option is C Assertion is correct but Reason is incorrect
1 mol hydrogen and nitrogen have same volume at same temperature and pressure.
$P V = n R T$ ---------- ideal gas equation.
Hence, at same temperature and pressure, $V \propto n$ .

1 mol gas at STP occupies 22.4 L volume.
Hence, Assertion is correct but Reason is incorrect.
