Solution
The correct option is A A - preformed antibodies, B - passive immunisation
Immunity is the ability of an organism to resist infections.
Immunisation is the process by which an individual's immune system becomes equipped with antibodies against antigens. Antigens are foreign substances that are able to trigger an immune response in an individual.
Immunisation is of two types, active immunisation and passive immunisation. In active immunisation, the immune system is stimulated to produce antibodies and lymphocytes. This can arise naturally when an individual is exposed to a pathogen or artificially when antigens are deliberately introduced into the individual. For example, oral polio vaccine is given to children to develop immunity against poliomyelitis virus.
Passive immunisation refers to the development of resistance to an infection in a non-immune individual by the administration of lymphocytes or preformed antibodies.
A bite from a venomous snake introduces deadly toxins inside the victim. This can have dangerous effects and can even be fatal in some cases. Treatment for snakebite requires injection of preformed antibodies into the patient to generate immunity as the patient does not have enough time to produce antibodies. This type of immunisation is called passive immunisation and is used during snakebites.

The chemical substances produced by certain microbes that can kill or retard the growth of other disease-causing microbes are called antibiotics.
