People administered with preformed antibodies get
(a) active immunity
(b) innate immunity
(c) natural immunity
(d) passive immunity

Options

A. active immunity
B. innate immunity
C. natural immunity
D. passiva immunity

Answer

To solve the question, we need to understand the different types of immunity and what is meant by "preformed antibodies."

1. **Understanding Preformed Antibodies**: Preformed antibodies are antibodies that are already made and can be administered to a person. This is different from the body producing its own antibodies in response to an infection or vaccination.

2. **Types of Immunity**:
- **Active Immunity**: This occurs when the body produces its own antibodies in response to an antigen (like a pathogen or vaccine). This type of immunity can be long-lasting.
- **Innate Immunity**: This is the natural defense mechanism that a person is born with. It includes physical barriers like skin and immune cells that respond to pathogens.
- **Natural Immunity**: This is a broader term that can refer to both innate and adaptive immunity that occurs through natural exposure to pathogens.
- **Passive Immunity**: This occurs when a person receives antibodies from another source, rather than producing them on their own. This can happen through maternal antibodies transferred to a fetus or through the administration of antibody-containing serum.

3. **Analyzing the Question**: The question states that people administered with preformed antibodies get a specific type of immunity. Since preformed antibodies are given directly, the body does not have to produce them. This aligns with the definition of passive immunity.

4. **Conclusion**: Based on the definitions and the context of the question, the correct answer is:
- (d) passive immunity
