Answer: Option B
Explanation: The population of prey inversely depends on the population of predators.
Predators are the organism that prey on other organism for their survival.
As they are inversely proportion to each other, more is the number of predators less is the number of prey and less is the number of predators more is the number of prey.
for example snake eat mouse, as here mouse is the prey and snake act as predator, if the population of snake decreases then the population of mouse will increase.
Thus, the correct answer is option B.
