Answer 2

Answer:

The right answer is B. Silicosis is a long-term lung condition caused by inhaling huge volumes of crystalline silica dust.

Explanation-

1. Bacillus anthracis, a gram-positive, rod-shaped bacterium, causes anthrax.
2. Silicosis is a chronic lung illness caused by inhaling significant volumes of crystalline silica dust, which causes swelling (inflammation) and eventually hardened and scarred lung tissue (fibrosis).
3. Emphysema is a lung disease that causes breathlessness. The air sacs (alveoli) in the lungs are destroyed in persons with emphysema. The inner walls of the air sacs weaken and rupture over time, resulting in bigger air gaps rather than numerous small ones.
4. A condition in which there is insufficient oxygen at the tissue level is hypoxia
