Solution

The correct option is B Silicosis
Silicosis is an occupational respiratory disorder. It usually happens in jobs where they breathe in dust that contains silica. That's a tiny crystal found in sand, rock, or mineral ores like quartz.

Botulism is a rare poisoning caused by toxins produced by Clostridium botulinum bacteria.

Anthrax is caused by a spore-forming bacterium Bacillus anthracis. It mainly affects animals. Humans can become infected through contact with an infected animal or by inhaling spores.

Emphysema is a lung condition that causes shortness of breath. In people with emphysema, the alveolar walls are damaged. This decreases the respiratory surface and, in turn, the amount of oxygen that reaches the bloodstream. Cigarette smoking is one of the major causes of this respiratory disorder
