Which of CH₄(g),C₂H₂(g),and CH₃OH(l)provides the Most Energy Per Gram Upon

Which of CH₄(g) ,C₂H₂(g) ,and CH₃OH(l) provides the most energy per gram upon combustion and which provides the least? CH₄(g) + 2 O₂(g) → CO₂(g) + 2 H₂O(l) ΔH° = -890 kJ
2 C₂H₂(g) + 5 O₂(g) → 4 CO₂(g) + 2 H₂O(l) ΔH° = -2599 kJ
2 CH₃OH(l) + 3 O₂(g) → 2 CO₂(g) + 4 H₂O(l) ΔH° = -1453 kJ

A) C₂H₂ provides the most energy per gram and CH₄ the least.
B) C₂H₂ provides the most energy per gram and CH₃OH the least.
C) CH₄ provides the most energy per gram and CH₃OH the least.
D) CH₄ provides the most energy per gram and C₂H₂ the least.
