Antivenom against snake poison contains

Options

A. (a) Antigens
B. (b) Antigen-antibody complexes
C. (c) Antibodies
D. (d) Enzymes

Answer

### Step-by-Step Solution:

1. **Understanding Antivenom**: Antivenom is a medical treatment used for snake bites. It consists of antibodies that neutralize the venom injected by the snake.

2. **Source of Antivenom**: Antivenom is produced by immunizing a host animal (like horses or sheep) with small amounts of snake venom. The animal's immune system produces antibodies against the venom.

3. **Extraction of Antibodies**: After the host animal has developed sufficient antibodies, blood is drawn from it, and the antibodies are purified to create the antivenom.

4. **Mechanism of Action**: When a person is bitten by a snake, they may take time to develop their own antibodies against the venom. Antivenom provides immediate passive immunity by supplying these ready-made antibodies.

5. **Composition of Antivenom**: The key component of antivenom is antibodies. It does not contain antigens, antigen-antibody complexes, or enzymes.

6. **Evaluating Options**:
- **Option A (Antigen)**: Incorrect, as antivenom contains antibodies, not antigens.
- **Option B (Antigen-antibody complexes)**: Incorrect, as antivenom does not contain these complexes.
- **Option C (Antibodies)**: Correct, as antivenom is composed of purified antibodies.
- **Option D (Enzymes)**: Incorrect, as antivenom does not contain enzymes.

7. **Conclusion**: The correct answer is that antivenom against snake poison contains antibodies.
