(B) The given process $X_{(g)} + e^- \to X^-_{(g)}$ represents the electron gain enthalpy of an atom $X$.When an electron is added to a neutral gaseous atom to form a gaseous anion,energy is generally released,making the process exothermic.For an exothermic process,the change in enthalpy $\Delta H$ is negative,i.e.,$\Delta H < 0$.
