The answer is B.a meteor strikes earth

Answer;

B. A meteor strikes Earth.

Explanation;Punctuated equilibrium  theory states that species stay the same for a long time and then change quickly because of environmental changes and new species arise.This theory predicts that a lot of evolutionary change takes place in short periods of time tied to speciation events.  According to this theory there is a very little change, and one or a few huge changes occur through mutations in the genes of a few individuals.
