A person is injected with the globulin against hepatitis. This is

Options

A. naturally acquired active immunity
B. naturally acquired passive immunity
C. artificially acquired active immunity
D. artificially acquired passive immunity

Answer

To determine the type of immunity a person receives when injected with globulin against hepatitis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Immunity**: Immunity is the body's ability to defend itself against foreign pathogens that cause diseases. It can be classified into two main types: innate immunity and adaptive immunity.

2. **Types of Adaptive Immunity**: Adaptive immunity is further divided into:
- **Naturally Acquired Immunity**: This can be either active or passive.
- **Naturally Acquired Active Immunity**: This occurs when a person is exposed to a live pathogen, gets infected, and then develops immunity.
- **Naturally Acquired Passive Immunity**: This occurs when antibodies are transferred from mother to child during pregnancy.
- **Artificially Acquired Immunity**: This can also be either active or passive.
- **Artificially Acquired Active Immunity**: This is induced by vaccines containing antigens, prompting the body to produce its own antibodies.
- **Artificially Acquired Passive Immunity**: This involves the injection of antibodies into a person, providing immediate but short-term protection.

3. **Analyzing the Question**: The question states that a person is injected with globulin against hepatitis. Globulin contains antibodies that provide immediate protection against the virus.

4. **Identifying the Type of Immunity**: Since globulin is injected to provide immediate immunity, this falls under artificially acquired passive immunity. This is because the person is receiving pre-formed antibodies rather than the body generating its own immune response.

5. **Conclusion**: Therefore, the correct answer to the question is **artificially acquired passive immunity**.

### Final Answer:
The correct answer is **artificially acquired passive immunity**.
