Answer:
B. The ability to fight disease caused by the pathogen will increase due to antibody production.
Step-by-step explanation:
"Vaccines" are considered very important especially when it comes to making the body immune to specific diseases.
In order for the body to know what the illness is, a "weakened pathogen" (antigens) is being introduced into the body. This causes a so-called "primary immune response," which means that the body will not experience the symptoms of the disease but its antibodies will get to know how to combat or fight the disease in the future.
