Assertion (A) : A patient suffering from tuberculosis should be quarantined.

Reason (R) : Tuberculosis is a bacterial infection.

Correct answer: (b) Both assertion(A) and reason(R) are true, but reason(R) is not the correct explanation for assertion.​

• Tuberculosis is caused by the bacterium Mycobacterium tuberculosis.​

• It is a communicable disease spread through respiratory droplets of an infected person when he sneezes or coughs or spits. ​

• So, patients suffering from tuberculosis should be quarantined to prevent and control the transmission.​

• Here, assertion and reason both are correct, but reason is not the correct explanation of the assertion.​
