Answer:
The correct answer is - active and passive.
Explanation:
Immunity is the capability of multicellular organism to protect itself from harmful molecules that are foreign to the body such as microorganism and antigens. Immunity can be active immunity or the passive immunity.
Active immunity takes place when one's own body produces antibodies to fight against a particular disease or antigen by immune system where as passive immunity occurs when an individual receives antibodies from outside and produced outside.
Thus, the correct answer is - active and passive.
