Which of the following corresponds to the definition of enthalpy of formation at \( 298 \mathrm{~K} \) ?
\( \mathrm{P} \)
(A) \( \mathrm{C} \) (graphite) \( +2 \mathrm{H}_{2}(\mathrm{~g})+1 / 2 \mathrm{O}_{2}(\mathrm{l}) \longrightarrow \mathrm{CH}_{3} \mathrm{OH}(\mathrm{g}) \)
(B) \( \mathrm{C} \) (diamond) \( +2 \mathrm{H}_{2}(\mathrm{~g})+1 / 2 \mathrm{O}_{2}(\mathrm{~g}) \longrightarrow \mathrm{CH}_{3} \mathrm{OH} \) (l)
W
(C) \( 2 \mathrm{C} \) (graphite) \( +4 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{CH}_{3} \mathrm{OH} \) (l)
(D) \( \mathrm{C} \) (graphite) \( +2 \mathrm{H}_{2}(\mathrm{~g})+1 / 2 \mathrm{O}_{2} \) (g) \( \longrightarrow \mathrm{CH}_{3} \mathrm{OH}( \) )
