Virus multiplies in

Options

A. Dead tessue
B. Soil
C. Living tissue
D. Culture medium.

Answer

**Step-by-Step Solution:**

1. **Understanding the Nature of Viruses**:
- Viruses are microscopic entities that consist of genetic material (either DNA or RNA) surrounded by a protein coat. They are classified as nucleoprotein particles.

2. **Inactivity Outside Host Cells**:
- Outside of a host cell, viruses are inert and cannot replicate or carry out metabolic processes. They exist in a dormant state, often referred to as virions.

3. **Requirement for Multiplication**:
- For a virus to multiply, it must enter a living host cell. Once inside, the virus can hijack the host's cellular machinery to replicate itself.

4. **Exclusion of Other Options**:
- Viruses cannot multiply in dead tissue, soil, or culture media.
- **Dead Tissue**: Lacks the necessary cellular machinery for viral replication.
- **Soil**: Does not provide a living host for viruses to infect.
- **Culture Medium**: While some viruses can be studied in lab settings, they cannot replicate outside of a living organism.

5. **Conclusion**:
- The only viable option for viral multiplication is living tissue, where the virus can become active and reproduce.

**Final Answer**: Virus multiplies in **living tissue**.
