What is the correct thermochemical equation for the formation of one mole of ethanol (C₂H₅OH)?

• A. 2C(graphite, s) + 3H₂(g) + ½O₂(g) → C₂H₅OH(l); ∆fH° = –277.7 kJ mol⁻¹
• B. C(graphite, s) + 3H₂(g) + ½O₂(g) → C₂H₅OH(l); ∆fH° = –277.7 kJ mol⁻¹
• C. 2C(graphite, s) + 6H(g) + O(g) → C₂H₅OH(l); ∆fH° = –277.7 kJ mol⁻¹
• D. C₂H₄(g) + H₂O(l) → C₂H₅OH(l); ∆fH° = –277.7 kJ mol⁻¹
