Question

Match List I with List II :

List - I		List – II
A.	B-Lymphocytes	i.	Passive immunity
B.	Interferons	ii.	Cell mediated immunity
C.	T-Lymphocytes	iii.	Produce an army of proteins in response to pathogens
D.	Colostrum	iv.	Innate immunity

Choose the correct answer from the options given below :

• A. A-I, B-IV, C-II, D-III
• B. A-IV, B-II, C-III, D-I
• C. A-III, B-IV, C-II, D-I
• D. A-II, B-IV, C-I, D-III

Answer 1

The Correct Option is C

To solve this question, we will match the given items in List I with the correct terms in List II that describe their functions or roles in biology:

1. B-Lymphocytes: These are a type of white blood cell responsible for producing antibodies. Antibodies are proteins used by the immune system to neutralize pathogens such as bacteria and viruses that enter the body. Hence, B-Lymphocytes form an "army of proteins in response to pathogens," which aligns with option iii.
2. Interferons: These are proteins that are part of the body's innate immunity system. They are released by host cells in response to the presence of pathogens such as viruses, bacteria, or parasites, and they help interfere with microbial replication. This matches option iv, which corresponds to "Innate immunity."
3. T-Lymphocytes: These cells are a crucial part of the immune system and are involved in cell-mediated immunity, which does not involve antibodies. Instead, they act directly against pathogens and infected cells. This matches option ii, representing "Cell mediated immunity."
4. Colostrum: This is the first form of milk produced by mammals immediately following delivery. It is rich in antibodies and provides passive immunity to the newborn, which corresponds to option i.

Based on the above explanations, the correct matches are:

• A - III: B-Lymphocytes - Produce an army of proteins in response to pathogens.
• B - IV: Interferons - Innate immunity.
• C - II: T-Lymphocytes - Cell mediated immunity.
• D - I: Colostrum - Passive immunity.

Therefore, the correct option is: A-III, B-IV, C-II, D-I
