The key word here that tells you the correct answer is "ignited". Ignite means to heat something until it reacts.
None of the other options imply any thing that would release energy - if simply mixing fuel oil and air released energy, you'd see flames if you spilled gasoline on the ground. Storing fuel oil at pressure doesn't make sense - oil by nature is liquid, and liquids are incompressible. Finally, d doesn't make sense either - cooling a gas doesn't release energy. That leaves c.
