Answer:
The correct answer is B. Phagocytosis.
Step-by-step explanation:
When antigens are coated with antibodies, it facilitates their recognition and binding by phagocytic cells such as macrophages and neutrophils. These phagocytic cells have receptors that specifically recognize the Fc portion of antibodies bound to antigens. Once recognized, the phagocytic cells engulf and internalize the antibody-coated antigens through a process called phagocytosis, leading to their destruction.
Option A is incorrect because once antigens are coated with antibodies, it actually enhances the immune response and does not make them more susceptible to further antibody attack. Option C refers to helper T cells, which play a role in activating other immune cells but are not directly involved in phagocytosis. Option D refers to B cells, which are responsible for producing antibodies but are not involved in the phagocytosis process.
Therefore, the correct answer is B. Phagocytosis.
