Which type of cell secretes antibodies?

Correct Answer: D

Rationale: Plasma cells are a type of white blood cell specialized in producing and secreting antibodies. Antibodies, also known as immunoglobulins, are vital components of the immune system that help recognize and neutralize pathogens. When the body encounters an antigen, plasma cells are activated to produce and secrete antibodies specific to that antigen. These antibodies bind to the pathogen, marking it for destruction by other immune cells. Therefore, plasma cells are the correct answer as they are specifically designed to produce and secrete antibodies to fight infections.
