Answer:

A. Tonsils trap pathogens from the air as it enters the body.

The immune system is a complex system of cells, tissues, and organs that work together to defend the body against harmful pathogens, such as bacteria, viruses, and parasites. Tonsils are a part of the immune system, as they act as a barrier against pathogens that enter the body through the mouth and nose. They trap and filter out harmful pathogens and other particles, helping to prevent infections in the body.
