Some models of portable "camp" stove use butane gas for fuel. This gas is reacted with the oxygen in the air to produce a flame for cooking. To start the stove, the user must first ignite the gas with a match or lighter.
Portable butane stove

Why does this combustion reaction need a small flame to get started?
Choose 1 answer:
(A) The flame provides the activation energy needed to trigger the reaction between butane and oxygen.
(B) The combustion reaction converts the thermal energy of the flame into chemical energy.
(c) The flame is an essential reactant in the combustion reaction.
