The most abundant type of WBC cells
- monocytes
- Basophils
- Neutrophils
- Eosinophils
The Correct Option is C
Approach Solution - 1
Neutrophils are a type of granulocyte and are the most common type of WBC found in the human body. They play a crucial role in the immune response, particularly in defending against bacterial infections. Neutrophils are highly mobile and are among the first cells to arrive at the site of infection or inflammation.
While all the options listed are types of WBCs, neutrophils are the most abundant, accounting for approximately 55-70% of the total WBC count in a healthy individual.
Therefore, the correct answer is (C) Neutrophils.
Approach Solution -2
The correct answer is:
Option 3: Neutrophils
Explanation:
Neutrophils are the most abundant type of white blood cells (WBCs) in human blood. They make up 50-70% of the total WBC count and play a crucial role in the body's immune system.
Functions of Neutrophils:
They are the first line of defense against infections.
They are phagocytic, meaning they engulf and destroy bacteria, viruses, and other pathogens.
They form pus at sites of infection due to their rapid response and accumulation.
Why the other options are incorrect?
Monocytes (Option 1) – The largest WBCs, but they are only about 2-10% of total WBCs. They become macrophages when they enter tissues.
Basophils (Option 2) – The least common WBCs, making up less than 1% of WBCs. They are involved in allergic reactions.
Eosinophils (Option 4) – Account for about 1-6% of WBCs and are mainly involved in allergic responses and parasitic infections.
Conclusion:
Since neutrophils make up the largest proportion of WBCs, the correct answer is Neutrophils (Option 3).

A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
