Answer: (A)

The primary function of the immune system is protection against disease. This complex network of cells, tissues, and organs works together to identify and eliminate pathogens such as bacteria, viruses, and parasites that can cause illness. The immune system plays a crucial role in recognizing harmful invaders and mounting an appropriate response, which can include the production of antibodies and the activation of various immune cells to target and destroy the pathogens. This protective mechanism is vital for maintaining overall health and resilience against infections. By effectively defending the body from diseases, the immune system helps to prevent potential health issues and supports recovery from illness, underscoring its critical role in survival and wellness.
