What is the correct balanced chemical equation that represents the complete combustion of 1,3,5-trimethylbenzene, a gasoline additive hydrocarbon?

• A. C₆H₁₆(l) + 10 O₂(g) → 8 H₂O(g) + 6 CO₂(g)
• B. C₉H₁₂(l) + 12 O₂(g) → 6 H₂O(g) + 9 CO₂(g)
• C. C₆H₁₂(l) + 9 O₂(g) → 6 H₂O(g) + 6 CO₂(g)
• D. C₉H₁₆(l) + 13 O₂(g) → 8 H₂O(g) + 9 CO₂(g)

Answer: (B)
