option A is correct, People with cystic fibrosis who live in tuberculosis-infected areas will be protected from tuberculosis because cystic fibrosis prevents it.

As a result, people in this region will die from cystic fibrosis rather than tuberculosis. Cystic fibrosis impacts the cells that control the production of secretions, perspire, and gastric enzymes. It creates the above fluids to coagulate and stick around each other. They then impede pipes, ducts, and passageways. Mycobacterium tuberculosis is the pathogen that causes tuberculosis (TB). TB microbes strike the respiratory system, but they will also inflict damage any area of the body, such as the liver, spine, and brain. Not everybody contaminated with tuberculosis becomes ill.
