According to the collision theory and model created to explain the collision theory, what is the best explanation for why a higher concentration makes a reaction go faster?

There are more collisions per minute.

It increases the distance between the particles.

It increases the average kinetic energy of the particles.

It increases the average kinetic energy and there are more collisions per minute.

first choice, the fourth answer is also correct but the question is all about the collision theory, thus, since there are more collisions, there is a greater probability that the chemical transformation (reaction) would occur.
