Compound $A$ is more polar and has more electronegative atoms than compound $B.$ When these two gases are mixed in a container and react to form compound $C(A+BC),$ it is expected that:

Neither of the molecules actually initiates the reaction. Both of them participate equally as they interact with each other

Molecules of compound A initiate the reaction by acting on molecules of type $B$

One of the molecules initiates the reaction, but either type of molecule can start the process by acting on the other

Molecules of compound $B$ initiate the reaction by acting on molecules of type $A$
