Slightly higher than that of chlorine

(C) The ionization energy $(IE)$ of hydrogen $(H)$ is $1312 \, kJ/mol$.The ionization energy $(IE)$ of chlorine $(Cl)$ is $1255 \, kJ/mol$.Since $1312 \, kJ/mol > 1255 \, kJ/mol$,the ionization energy of hydrogen is slightly higher than that of chlorine.Therefore,the correct option is $(C)$.
