MHT CET Chemistry question

Enthalpy of formation of HF and HCl are kJ and kJ, respectively. Which of the following statements is incorrect?

(A)HCl is more stable than HFCorrect
(B)HF and HCl are exothermic compounds
(C)The affinity of fluorine to hydrogen is greater than the affinity of chlorine to hydrogen
(D)HF is more stable than HCl

Answer: (A)

HF has the more negative enthalpy of formation ( vs kJ), so more energy is released on forming it and HF is more
