25℃、101 kPa下，碳、氢气、甲烷和葡萄糖的燃烧热依次是393.5 kJ/mol、285.8 kJ/mol、890.3 kJ/mol、2 800 kJ/mol,则下列热化学方程式正确的是                                                                                                     

A：C(s)+O₂(g)='CO(g)' △H=' -393.5' kJ/mol

B：2H₂(g)+O₂(g)=2H₂O(g)△H='+571.6' kJ/mol

C：CH₄(g)+2O₂(g)=CO₂(g)+2H₂O(g)△H=' -890.3' kJ/mol

D：C₆H₁₂O₆（s）+3O₂(g)=3CO₂(g)+3H₂O(l)△H=' -1' 400 kJ/mol
