For this, you have to form a balanced equation for the combustion of each of them. The one that forms a balanced equation with 8O2 is the correct one.
The answer is B, because...
C6H9OH + 8O2 -----> 6CO2 + 5H2O
You can form a balanced equation with B, so B is the answer

Hmm, like?
The main thing is that, only one molecule of each organic compound is to be used in your equation.
