Very great question.
Ethane seems to be the answer at the first glance but it is actually not.
2 C X 4 H X 1 0 + 5 O X 2 8 C O X 2 + 1 0 H X 2 O
So, 2 moles of butane gives 8 moles of carbon dioxide and 1 0 moles of carbon dioxide.
So, 1 mole of butane gives 4 moles of carbon dioxide and 5 moles of carbon dioxide.
Sp, the answer is Butane .
