Rayon is obtained from:

Options

A. Coal, water and oil
B. Wood-pulp
C. Acrylic
D. Animals

Explanation

**Step-by-Step Solution:**

1. **Understanding Rayon**: Rayon is a type of fiber that is often used in textiles. To determine its source, we need to identify what materials can be used to produce Rayon.

2. **Evaluating Options**: The options provided are:
- A) Coal, water, and oil
- B) Wood
- C) Acrylic
- D) Animals

3. **Analyzing Each Option**:
- **Option A (Coal, water, and oil)**: While these materials are used in various industrial processes, they do not contain the necessary components to produce Rayon.
- **Option B (Wood)**: Wood contains cellulose, which is a natural polymer. Rayon is derived from wood pulp, which is chemically treated to extract cellulose and then regenerated into fibers.
- **Option C (Acrylic)**: Acrylic is a synthetic polymer and cannot be the source of Rayon, which is derived from natural materials.
- **Option D (Animals)**: Animal products are not used to produce Rayon, as Rayon is plant-based.

4. **Conclusion**: Since Rayon is primarily obtained from wood pulp, which contains cellulose, the correct answer is **Option B (Wood)**.

5. **Final Statement**: Rayon is obtained from wood pulp, making it a semi-synthetic fiber due to its natural and chemical processing.
