The injection given against the snake venom contains

Options

A. antigenic proteins
B. preformed antibodies
C. attenuated pathogen
D. all of these.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what the injection given against snake venom contains. Snake venom is a type of toxin, and the injection used to counteract it is known as an antivenom or antitoxin.

2. **Identifying the Components of Antivenom**: Antivenom is specifically designed to neutralize the effects of venom. It contains preformed antibodies that can quickly bind to the venom and neutralize its effects.

3. **Passive Immunity**: The preformed antibodies in antivenom provide passive immunity. This means that the antibodies are given directly to the person, providing immediate protection without the need for the body to produce its own antibodies.

4. **Evaluating Other Options**:
- **Antigenic Proteins**: These are proteins that can stimulate an immune response, but they take time to generate antibodies and are not used in emergency situations like snake bites.
- **Attenuated Pathogens**: These are weakened forms of pathogens used in vaccines to stimulate an active immune response. This is also not applicable in the case of snake venom treatment.
- **All of These**: Since only preformed antibodies are relevant in this context, this option is incorrect.

5. **Conclusion**: Based on the above analysis, the correct answer to the question is that the injection given against snake venom contains **preformed antibodies**.

**Final Answer**: The injection given against the snake venom contains **preformed antibodies**.
