Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The question asks to identify the disease that is not transmitted through the consumption of or contact with contaminated water (i.e., it is not a water-borne disease).

Step 2: Detailed Explanation:
- Cholera, Dysentery, and Typhoid are classic examples of water-borne diseases. They are caused by bacteria that are spread through water contaminated with the feces of an infected person.
- Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It is primarily an airborne disease, spreading from person to person through tiny droplets released into the air via coughs and sneezes.

Step 3: Final Answer:
Cholera, Dysentery, and Typhoid are water-borne, whereas Tuberculosis is airborne. Therefore, Tuberculosis is not caused by contaminated water.
