Question

A)	Naturally acquired ACTIVE IMMUNITY	i)	Jasmine was vaccinated for Polio to protect her against the disease.
B)	Artificially acquired ACTIVE IMMUNITY	ii)	Rohit was bitten by a viper and was given an injection of anti-venom.
C)	Naturally acquired PASSIVE IMMUNITY	iii)	Imran suffered from Chicken pow in childhood and is now possibly immune to another chickenpox attack.
D)	Artificially acquired PASSIVE IMMUNITY	iv)	Ria was advised by doctors to breastfeed her newborn in order to improve the infant's immunity.

Immunity can be gained actively or passively. When the antibodies to antigens are produced by our own bodies, we call it active immunity. We acquire passive immunity by receiving antibodies that were not made by our own bodies. Which of the following options is the correct match for the type of immunity with the appropriate example?

• A. $A\to i,B\to iii,C\to ii,D\to iv$
• B. $A\to iii,B\to i,C\to iv,D\to ii$
• C. $A\to i,B\to iii,C\to iv,D\to ii$
• D. $A\to iii,B\to i,C\to ii,D\to iv$

Answer 1

The correct option is B $A\to iii,B\to i,C\to iv,D\to ii$

When our immune system itself provides antibodies for the protection it is called naturally acquired active immunity and when the baby receives the immunity from the mother is called naturally acquired passive immunity similarly if we take a vaccine for a virus it's artificial but antibodies are produced by the immune system but in an emergency, anti-bodies are not made by the immune system but acquired from external source hence called artificially acquired passive immunity.

So the correct option is B.
