The causative agent of Tuberculosis is Mycobacterium. Tuberculosis (TB) is an infectious disease that primarily affects the lungs. Mycobacterium tuberculosis, a bacterium, is responsible for causing TB. This bacterium is transmitted through the air when an infected person coughs, sneezes, or speaks. It can also spread to other parts of the body, such as the kidneys, spine, and brain, causing extrapulmonary TB.
Option 2, Aspergillus, is incorrect because Aspergillus is a type of fungus and is not associated with causing Tuberculosis.
Option 3, Rhabdovirus, is incorrect because Rhabdovirus is a family of viruses that includes the rabies virus, not the bacterium causing Tuberculosis.
Option 4, Hrv, is irrelevant as it does not correspond to any known causative agent of Tuberculosis.
Therefore, the correct answer is option 1, Mycobacterium.
