C Correct answer
Explanation

Tuberculosis is caused by Mycobacterium tuberculosis, which primarily infects the lungs. While TB can affect other organs (extrapulmonary TB), the lungs are the most common and primary site of infection when the bacteria enter the body. The gut, heart, and brain are not the typical entry points or primary targets.
