Injection of an antidote against snakebite is an example of
- Passive immunity
- Auto immunity
- Innate immunity
- Active immunity
The Correct Option is A
Approach Solution - 1
Passive immunity involves the direct transfer of pre-formed antibodies (e.g., antidote/snakebite antivenom) to provide immediate but temporary protection.
Example: Antidote for snakebite contains antibodies against venom.
- (A) Innate immunity: Non-specific defense (e.g., skin, phagocytes).
- (B) Active immunity: Long-term protection via self-produced antibodies (e.g., vaccines).
- (D) Autoimmunity: Immune system attacks self-tissues (e.g., Type 1 diabetes).
Approach Solution -2
Passive immunity involves preformed antibodies (antidote) injected to provide immediate, short-term protection.
Passive immunity is a form of immunity that occurs when an individual is given antibodies or immune cells from another source, rather than producing them through their own immune system. This type of immunity provides immediate protection but is temporary, as the antibodies are eventually broken down by the body.
- Contrast with:
- (B) Active immunity: Body produces its own antibodies (e.g., vaccines).
- (A) Innate immunity: Non-specific defenses (e.g., skin, macrophages).
- (D) Autoimmunity: Immune system attacks self-tissues.
Correct Answer: (C) Passive immunity

Concepts Used:
Immune System
It consists of tissues, cells, soluble molecules like antibodies and lymphoid organs. The WBC cells called the leucocytes have a significant role as they seek out to destroy the disease-causing organisms. These leucocytes are stored in different locations in the body including the spleen, bone marrow, and thymus. These organs are called as the lymphoid organs. The leucocytes are also present in the lymph nodes of the body.It is considered as the main lymphoid orga and. It produces all the blood cells including the lymphocytes. The thymus is an organ that is present near to the heart, beneath the breastbone.
