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 $\displaystyle -57 \mathrm{~kJ} \mathrm{~mol}^{-1}$ Reason (R) : Enthalpy of neutralisation is the amount of heat liberated when one mole of $\displaystyle \mathrm{H}^{+}$ ions furnished by acid combine with one mole of $\displaystyle { }^{-} \mathrm{OH}$ 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.
