Which of the following set of equations could be used to represent the standard enthalpy of formation of glucose?

A. 6C(s) + 6H2(g) + 3O2(g) → C6H12O6(s)
B. 6CO2(g) + 6H2O(l) → C6H12O6(s) + 6O2(g)
C. 6C(g) + 6H2(g) + 3O2(g) → C6H12O6(s)
D. 6C(g) + 6H2(g) + 3O2(g) → C6H12O6(aq)

Correct Answer: Option B

B. 6CO2(g) + 6H2O(l) → C6H12O6(s) + 6O2(g)
