C. Hunting Wolves
Is the human activity that most likely resulted in the growth of the North American deer population.
Wolves hunt deer. The decrease in the population of predators will increase the number of preys living in their shared environment.
Hunting of bisons will not have any effect on the deer population. Bisons are herbivores. They don't eat deer.
