Answer 1

Answer:

A. Initiating the immune response

The main function of leukocytes, also known as white blood cells, is initiating the immune response. They protect the body against infectious diseases and foreign invaders. White blood cells are a part of your immune system that protects your body from infection. These cells circulate through your bloodstream and tissues to respond to injury or illness by attacking any unknown organisms that enter your body.
