The correct answer is option B
Predators and parasite feed on other living organisms for their food. Predators kill the other living organisms for their food. Parasite also feed on other living organisms for food. They survive in the body of the host (living body) and get nutrition from them. The Predators kill other animals for their food. The only difference is that the predators eat the whole prey but parasites only depend on the host for the purpose of food.
