The correct option is A 22.4 litres
Standard temperature & pressure(STP) conditions imply a temperature $273.15 k$ and a pressure of $1 a t m$ . When these conditions meet, one mole of any gas occupies $22.4 l i t r e s$ exactly.
$\Rightarrow$ At STP, one mole of a gas occupies $22.4 l i t r e s$ of volume.
