A. C5H12 + 5.5O2 –> 5CO2 + H2O
B. C5H12 + 4O2 –> 5CO2 + 3H2O
C. C5H12 + 8O2 –> 5CO2 + 6H2O
D. C5H12 + 4O2 –> CO2 + 6H2O

Well, we need to add up all the atoms on each side and see if the equation is balanced.
The answer is C, and we can see that by adding up the atoms.
On the left side, there are 5 carbon atoms, 12 hydrogen atoms, and 16 oxygen atoms.
On the right side, there are 5 carbon atoms, 12 hydrogen atoms, and 5*2+6= 16 oxygen atoms.
Both sides have the same number of atoms, and you don’t have to worry about charges or anything like that for this equation, so the answer is C.

C.
Count the atoms on both sides of the equation-
C5H12 + 8O2
5 C atoms
12 H atoms
16 O atoms
5CO2 + 6O2
5 C atoms
12 H atoms
16 O2 atoms (10 in 5CO2 + 6 in 6H2O)

C. 5 carbon, 12 hydrogen, and 16 oxygen atoms on each side of the reaction.
