Question

Match the following cells of immune system List I with their functions List II:

	List I-Immune sytem		List II-Functions
A	Mast cells	I	Master of immune system
B	Lymphocytes	II	Allergic reactions
C	T-cells	III	Cell mediated immune reactions
D	Monocytes- Macrophages	IV	Antigen recognition, Phagocytosis

Choose the correct answer from the options given below:

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

Answer 1

The Correct Option is B

To match the immune system cells from List I with their corresponding functions in List II, we need to understand the specific roles of each cell type in the immune response: 

1. Mast Cells: These cells play a significant role in allergic reactions. They release histamine and other chemicals during allergic responses, leading to symptoms like inflammation and itching. Thus, the correct match for mast cells is II: Allergic reactions.
2. Lymphocytes: These cells are fundamental players in the immune system's function. They are involved in recognizing and responding to antigens, making them the 'master' coordinators of the immune response. Hence, the best match here is I: Master of immune system.
3. T-cells: A type of lymphocyte, T-cells are essential for cell-mediated immunity, which involves directly attacking infected cells or coordinating other parts of the immune system. The appropriate function match for T-cells is III: Cell mediated immune reactions.
4. Monocytes-Macrophages: These cells are crucial for phagocytosis, where they engulf and digest cellular debris and pathogens. They also play a role in antigen recognition and presentation to other immune cells. Therefore, the most fitting function is IV: Antigen recognition, Phagocytosis.

Based on this understanding, the correct matching sequence for List I and List II according to the question options is: A-II, B-I, C-III, D-IV.

	List I - Immune system		List II - Functions
A	Mast cells	II	Allergic reactions
B	Lymphocytes	I	Master of immune system
C	T-cells	III	Cell mediated immune reactions
D	Monocytes-Macrophages	IV	Antigen recognition, Phagocytosis
