Methane (ch4) burns in oxygen to produce carbon dioxide and water. which reaction is occurring here?

The type of reaction that occur  when  (CH4)  burns in oxygen to produce carbon dioxide and water  is combustion reaction

   explanation

 Combustion reaction is type of chemical reaction in which  a compound  and oxidant react to produce  heat and  new product.

when a hydrocarbon for example methane    undergoes combustion it produces  carbon (iv) oxide, water and heat  according to reaction below.

CH4 + 2O2  →  CO2 + 2H2O  + heat

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

is there any options? maybe im just not seeing them but i need the options to
