Solution

The correct option is D 40 L
Initially when $T = 0$ :
$3 O_{2} 00 \to 2 O_{3} 0$
At TK total volume of oxygen and ozone is $100$ litre hence after time T when the reaction is completed total volume of oxygen and ozone will be:
$100 - 3 x = 2 x$
$∵ 100 - 3 x = 2 x$
or $x = 20$
$∴$ Volume of ozone $= 2 x = 40 L$
