Final Answer :
C
Explanation :
Eosinophils are specialized white blood cells that are involved in fighting parasitic infections, particularly those caused by helminths (worms) that are too big for phagocytosis by other immune cells. Eosinophils release toxic granules that damage the parasites, and they also secrete cytokines that attract and activate other immune cells to help in the elimination of the invaders. Basophils and dendritic cells are also involved in immune responses, but they do not have as specific a role in fighting parasites as eosinophils do. Lymphocytes and neutrophils can also help in the response to parasitic infections, but they are not specifically adapted to attack parasites that are too big for phagocytosis.
