A. combusting and giving off energy to jump start a reaction.
B. lowering the activation energy of a reaction.
C. boosting the energy of the particles to meet the activation energy threshold.
D. binding to low energy particles to keep them out of the way of the high energy particles to increase the rate of collisions.​

Answer 1

Answer:

B. lowering the activation energy of a reaction

by lowering the activation energy, it uses less energy to start the reaction which will speed up the reaction time
