B. Passive immunity
C. Active immunity
D. Nonspecific immunity

Answer

To answer the question "Production of antibodies against antigens in the body is referred to as," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Antigens**:
- Antigens are substances that can provoke an immune response, typically found on the surface of pathogens like viruses and bacteria.

2. **Role of Antibodies**:
- Antibodies are proteins produced by the immune system in response to antigens. Their primary function is to identify and neutralize foreign objects like bacteria and viruses.

3. **Immune Response**:
- When an antigen enters the body, the immune system recognizes it as foreign and responds by producing antibodies specifically tailored to that antigen.

4. **Types of Immunity**:
- There are different types of immunity, including passive immunity (where antibodies are transferred from another source) and active immunity (where the body produces its own antibodies).

5. **Defining Active Immunity**:
- The production of antibodies by the immune system in response to an antigen is known as active immunity. This can occur naturally (through infection) or artificially (through vaccination).

6. **Conclusion**:
- Therefore, the correct term for the production of antibodies against antigens in the body is "active immunity."

### Final Answer:
The production of antibodies against antigens in the body is referred to as **active immunity**.
