Statement I :

A person may suffer from tuberculosis if she/he frequently visits crowded place.

Statement II :

Bacteria of tuberculosis spread through droplets by sneezing or coughing.

A) Both the statements are individually true and Statement II is the correct explanation of Statement I	B) Both the statements are individually true but Statement II is not the correct explanation of Statement I
C) Statement I is true but Statement II is false	D) Statement I is false but Statement II is true

Answer & Explanation Answer: D) Statement I is false but Statement II is true

Explanation:

Tuberculosis (TB) is caused by a type of bacterium called Mycobacterium tuberculosis.

It's spread when a person with active TB disease in their lungs coughs or sneezes and someone else inhales the expelled droplets, which contain TB bacteria.

One would have to spend prolonged periods (several hours) in close contact with an infected person to catch the infection yourself.For example, TB infections usually spread between family members who live in the same house. It would be highly unlikely for you to become infected by sitting next to an infected person on a bus or train. Hence, statement 1 is incorrect.
