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