Small structures related to the lymphatic vessels, alone or in groups, that function as filters for the lymph and center of lymphocyte production are called lymph nodes (option c).
Explanation:
Lymph nodes, also called lymph ganglia, are structures of the lymphatic system that are found in the path of lymph-conducting vessels, similar to a bean.
The main functions of the lymph nodes are to filter the lymph that passes through them and to be the center of lymphocyte production, both functions related to the body's defenses and immune system.
On the occasion of an infection, the lymph nodes adjacent to the affected area can become swollen and painful, a sign that pathogens are being fought in them.

<em> b. </em><em><u>Heart nodes</u></em><em> refer to the small structures that are responsible for nerve conduction and automation in that organ.</em>
