Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R) Assertion (A) : Enthalpy of neutralisation of strong monobasic acid with strong monoacidic base is always −57 kJ mol−1. Reason (R) : Enthalpy of neutralisation is the amount of heat liberated when one mole of H+ ions furnished by acid combine with one mole of OH− ions furnished by base to form one mole of water. In the light of the above statements, choose the correct answer from the options given below.

Electricity is passed through an acidic solution of $\mathrm{Cu}^{2+}$ till all the $\mathrm{Cu}^{2+}$ was exhausted, leading to the deposition of 300 mg of Cu metal. However, a current of 600 mA was continued to pass through the same solution for another 28 minutes by keeping the total volume of the solution fixed at 200 mL. The total volume of oxygen evolved at STP during the entire process is $\_\_\_\_$ mL.
