Options

A. Chromosome
B. Nucleus
C. Cell
D. Tissue

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the smallest viable unit that can grow, multiply, and form a plant in tissue culture.

2. **Identifying Options**: The options provided are:
- a. Chromosome
- b. Nucleus
- c. Cell
- d. Tissue

3. **Analyzing Each Option**:
- **Chromosome**: This is a structure within the cell that contains DNA, but it is not capable of growing or multiplying on its own.
- **Nucleus**: This is the control center of the cell, containing genetic material, but it cannot grow or multiply independently.
- **Cell**: A cell is the basic unit of life. It can grow, multiply, and is capable of forming a new plant when cultured properly.
- **Tissue**: This is a group of cells that work together, but it is not the smallest unit that can independently grow and multiply.

4. **Conclusion**: After analyzing the options, it is clear that the smallest viable unit that can grow, multiply, and form a plant in tissue culture is the **cell**.

5. **Final Answer**: Therefore, the correct answer is option **C. Cell**.
