Answer:
The correct answer is d. Tenderness and redness at the site
Step-by-step explanation:
Immunization is the process by which unharmful antigens(vaccine) are administered in a person's body so that the person develops memory against that antigen and become immune to that antigen.
After immunization antigen-antibody reactions start in the body which can give symptoms like redness in leg or arm where the vaccine was administered, swelling in the vaccinated area, soreness or tenderness in the vaccinated region, and pain.
