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.

1. A (\(A\)) is true but (\(R\)) is false
2. B Both (\(A\)) and (\(R\)) are true and (\(R\)) is the correct explanation of (\(A\))
3. C (\(A\)) is false but (\(R\)) is true
4. D Both (\(A\)) and (\(R\)) are true but (\(R\)) is not the correct explanation of (\(A\))
