Which of the following eations has \(\Delta_{f} \mathrm{H}^{\circ}\) and \(\Delta \mathrm{H}^{\circ}\) same?

1. A \(\mathrm{H}_{2(\mathrm{~g})}+\frac{1}{2} \mathrm{O}_{2(\mathrm{~g})} \longrightarrow \mathrm{H}_{2} \mathrm{O}_{(\mathrm{l})}\)
2. B \(\mathrm{N}_{2(\mathrm{l})}+\mathrm{O}_{3(\mathrm{~g})} \longrightarrow \mathrm{N}_{2} \mathrm{O}_{3(\mathrm{~g})}\)
3. C \(\mathrm{CH}_{4(\mathrm{~g})}+2 \mathrm{Cl}_{2(\mathrm{~g})} \longrightarrow \mathrm{CH}_{2} \mathrm{Cl}_{2(\mathrm{~g})}+2 \mathrm{HCl}_{(\mathrm{g})}\)
4. D \(\mathrm{CO}_{(\mathrm{g})}+\mathrm{O}_{2(\mathrm{~g})} \longrightarrow 2 \mathrm{CO}_{2(\mathrm{~g})}\)
