Answer:

The correct answer would be B. They destroy pathogens that enter the wound.  

White blood cells (WBC) are the component of the immune system in a body.

Their main function is to protect our body against pathogens and foreign invaders.  

They can be broadly classified into five types namely eosinophils, neutrophils, basophils, monocytes, and lymphocytes.

They achieve this function by:

  • Phagocytosis  
  • Producing antibodies against the foreign invaders.
  • Producing antitoxins to neutralize the toxins produced by the pathogen.
