Three states of matter are the result of?

The following question has four choices out of which ONLY ONE is correct.

An empty 2.0 l vessel is filled with CH₄ (g) at 1.00 atm and O₂ (g) at 4.00 atm, at 300^oC. A spark causes CH₄ to burn completely according to the equation:

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g), ∆H = – 802 kJ

Partial pressure of oxygen inside the vessel after combustion is
