Final answer:
Antibodies help destroy antigens by interfering with their functions, clumping them together, and stimulating the complement system. Phagocytic cells are attracted to the antigen-antibody complexes and enhance the process of phagocytosis.
Step-by-step explanation:
Antibodies help destroy antigens by binding to them and interfering with their ability to infect or bind to other cells. Antibodies can also create bridges between different particles containing antigenic sites, clumping them together and preventing their proper functioning.
Additionally, the antigen-antibody complex stimulates the complement system, leading to the destruction of the cell bearing the antigen.
Phagocytic cells are attracted by antigen-antibody complexes and enhance the process of phagocytosis.
Therefore, all of the options presented in the question (a) antibodies, (b) phagocytes, (c) lymphocytes, and (d) allergens, do not help destroy antigens but rather contribute to their destruction.
