The Balanced Equation for the Combustion of Propane Is Given

The balanced equation for the combustion of propane is given below. What do the numbers in front of the molecules (the coefficients) mean? CH₃CH₂CH₃ + O₂ → 3 CO₂ + 4 H₂O

A) Three molecules of CO₂ are produced when one molecule of CH₃CH₂CH₃ reacts with one molecule of O₂.
B) Six molecules of CO₂ are produced when two molecules of CH₃CH₂CH₃ react with two molecules of O₂.
C) Nine moles of CO₂ are produced when three moles of CH₃CH₂CH₃ react with three moles of O₂.
D) Four moles of H₂O are produced when one mole of CH₃CH₂CH₃ reacts with one mole of O₂.
E) All of the above
