Show answer and solution
Answer: (D) a bacterium, Mycobacterium tuberculosis
Tuberculosis, mainly affecting the lungs, is caused by the bacterium Mycobacterium tuberculosis and spreads through droplets when an infected person coughs or sneezes. It is treated with antibiotics over a prolonged period, and the BCG vaccine gives protection. Plasmodium causes malaria, and tuberculosis is not caused by a virus or a fungus.
