Hint: Anti-microbial means the substances that are used to destroy all the types of microorganisms, i.e., bacteria, viruses, fungus, etc. These are of three types which can be taken inside the body, that can be applied to the body, and on the non-living components.

Complete answer:
In nature, there are many good things that are beneficial for us and there are many bad things that can harm us. And we try to stay away from these bad things that cause harm. So, some of these things are microorganisms like bacteria, viruses, fungus, etc. They can be present on living things as well as non-living things.
So, for these we use antimicrobials. Anti-microbial means the substances that are used to destroy all types of microorganisms. These are of three types which can be taken inside the body, that can be applied to the body, and on the non-living components.
Those antimicrobials that can be taken inside the body are known as Antibiotics. When we get wounds, cuts, or burns it needs to be cared for properly otherwise micro-organism can worsen the situation so, on living objects we use antiseptics. But if we want to clean floors, windows, doors, etc which are non-living substances we use disinfectants.
A tranquilizer is a medication that is used to relieve anxiety, terror, stress, agitation, and other mental disorders, with the goal of reducing anxiety and tension.

Therefore, the correct answer is an option (b)- Tranquilizers.

Note:
An example of antibiotics is penicillin, etc. An example of antiseptic is tincture of iodine while an example of disinfectant is 1% phenol solution. 0.2% of phenol solution is suited as antiseptic as well as disinfectant.
