Solution

The correct option is B Negative
In the process $C l (g) + e Δ H - - \to C l (g), Δ H$ is negative.

The process represents electron gain enthalpy of chlorine. Energy is released when an electron is added to the gaseous chlorine atom. Chlorine has the most negative value of electron gain enthalpy. It is equal to -348.3 kJ/mole.

Hence, the correct option is $B$
