Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : … in water is more stable than …. Reason (R) : Enthalpy of hydration for … is much less than that of …. In the light of the above statements, choose the correct answer from the options given below :
