The standard enthalpy of formation $(\Delta H_f^{\circ})$ at 298 K for methane, $CH_4 (g)$, is $-74.8 \; kJ\;mol^{-1}$. The additional information required to determine the average energy for $C-H$ bond formation would be :

Question

( A ) the dissociation energy of hydrogen molecule, $H_2$
( B ) the dissociation energy of $H_2$ and enthalpy of sublimation of carbon
( C ) the first four ionization energies of carbon and electron gain enthalpy of hydrogen
( D ) latent heat of vaporization of methane
