Answer:
D, The white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.
Explanation:
Vaccinations are essentially just weak diseases we use to create antibodies so the body can protect itself from the full disease. If it sees it once, it can defend itself, is the theory. This is choice D.
- Why not A: The weakened form will be attacked by the immune system, but maybe not enough, because the person is so sick that the immune system is busy elsewhere.

- Why not C: The digestive system isn't the issue. You don't eat diseases.
You should expect an endangered species to be more SPECIALIST. Animal species that can live in different types of environment and which can survive on different types of food are called generalist. This type of animal specie can not be easily endangered because they have high level of survival. The specialist animal species on the other hand are adapted to a narrow range of food and environment. Specialist species can be easily wipe out if there food resources is exhausted or if their habitat is destroyed.
