  4. Anthrax
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Anthrax is a highly contagious and infectious soil-borne disease caused by Bacillus anthracis, a relatively large spore-forming bacteria that can infect mammals. Anthrax is primarily a disease of herbivores, particularly bison and beef cattle. Anthrax infections are rare in humans. Beef cattle and bison are most likely to contract the disease because they graze lower to the ground than many other herbivores, often due to drought or management practices. It is also believed that the abrasive forages they consume can injure the mouth and allow the bacteria quick access to the bloodstream. 

So the correct option is D, Anthrax
