Ans.
Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.

Explanation:
Depending on the physical characteristics only, we can see that the organisms shown in number 1 and in number 3 are similar o one another but not purely identical. This means that these organism are closely related to one another.
The organisms shown in option 2 and 4 are not very similar to one another depending on the physical characteristics. Hence, we can say that organisms shown in number 1 and number 3 are more closely related to one another s compared to the organism shown in option 2 and 4.
