b) natural selection
Natural selection states that the organisms which are fit to survive in the existing environment reproduce and increase in number while other die and perish away. Certain changes take place in the organisms which adapt themselves better and these variation are passed to next generation increasing their chances of survival that the others. This theory was given by Charles Darwin and is based on survival of fittest.
