A. Neutrophils
B. Eosinophils
C. Basophils
D. Lymphocytes
E. Monocytes
Choose the correct answer from the options given below :
Leukocytes, commonly known as white blood cells (WBCs), are crucial components of the human immune system. They circulate in the blood and lymph fluid.
Human blood leukocytes comprise several distinct types of cells, each with specific functions. These include:
All the cell types listed (Neutrophils, Eosinophils, Basophils, Lymphocytes, and Monocytes) are recognized types of leukocytes found in human blood. Therefore, the correct option must include all of them.
Option 4 correctly identifies that Neutrophils (A), Eosinophils (B), Basophils (C), Lymphocytes (D), and Monocytes (E) are all found in human blood leukocytes.
