Answer
A. Lymph nodes
Explanation
Lymph fluid circulates through the body's lymphatic system and plays a key role in the immune system by removing waste and toxins. Each option plays a role in the immune system, but their functions differ significantly:1. **Lymph nodes** are small, bean-shaped structures that act as filters for lymph fluid. They trap bacteria, viruses, and other foreign substances, which are then destroyed by specialized cells called lymphocytes.2. **Thymus** is involved in the development of T-lymphocytes (T cells), a type of white blood cell that plays a critical role in the immune response.3. **Tonsils** are part of the body's first line of defense in the immune system. They trap germs (bacteria and viruses) which you may breathe in.4. **Spleen** helps filter blood, removing old or damaged blood cells and pathogens, but it is not the primary structure for filtering lymph fluid.Given this information, the structure specifically responsible for filtering lymph fluid is the lymph nodes.
