the correct answer option is b. the population of predators will increase first and then decrease slowly.
there is a stable number of predators and prey in any given environment that it can maintain.
if there is an increase in the number of prey, then there would also be an increase in the number of predators to compensate that increase of prey.
however, as soon as the population gets balanced again, the population of predators would slowly decrease back to its original number.
