Explanation:
Detailed explanation-1: -The correct answer is B) chemotaxis, adherence, ingestion, digestion, killing.
Detailed explanation-2: -In the first step of phagocytosis, phagocytes are attracted by and move toward a variety of substances generated in the immune response; this process is called chemotaxis. Resting phagocytes are activated by inflammatory mediators (bacterial products, cytokines, prostaglandins, and complement proteins).
Detailed explanation-3: -Attachment of phagocytes to the microbes or cells can be through unenhanced attachment or enhanced attachment. Unenhanced attachment is the recognition of pathogen-associated molecular patterns or PAMPs by endocytic pattern-recognition receptors on the surface of the phagocytes.
