Option C. Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies.

Explanation:

Active and passive immunity both use the body's response to fight against pathogens. The immunity sets the body defense mechanism to be on alert against any disease-causing pathogens. In the active immunity, the body's immunity cells, the T-lymphocytes, are responsible for fighting the disease. They do this by storing the memory about the pathogen and allow the lymphocytes to engulf the pathogen. On the other hand, the passive immunity is vaccine-based. The immunity improves the body's mechanism by instilling a memory mechanism in order to fight the disease. Both are memory based immunity systems.
