(B) $20$ volume $H_2O_2$ means that $1 \, mL$ of $H_2O_2$ solution produces $20 \, mL$ of $O_2$ gas at $N.T.P$.Given volume of $H_2O_2$ solution = $15 \, mL$.Volume of $O_2$ liberated = $(\text{Volume of solution}) \times (\text{Volume strength of } H_2O_2)$.Volume of $O_2$ liberated = $15 \, mL \times 20 = 300 \, mL$.
