signal travels at the speed of light, that is 3x 109 ms‐1

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.

Ithink the answer is d i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
