Solution

The correct option is A PMNL-neutrophilis
Innate immunity refers to nonspecific defence mechanisms that come into play immediately or within hours of an antigen's appearance in the body. These mechanisms include physical barriers such as skin, chemicals in the blood, and immune system cells such as neutrophils that attack foreign cells in the body. Polymorphonuclear leukocytes (PMNL - neutrophils) are the granulocytes characterized by the presence of granules in their cytoplasm. They provide innate immunity.
So, the correct answer is 'PMNL-neutrophils'.
