The commercial jute fibres are obtained from

Options

A. sieve fibres
B. xylem fibres
C. phloem fibres
D. fibres of mesocarp of coconut

Answer

**Step-by-Step Solution:**

1. **Understanding Jute Fibres**: Jute is a natural fiber that is primarily used for making burlap, hessian cloth, and various other products. It is known for its strength and durability.

2. **Identifying the Source of Jute Fibres**: Jute fibers are derived from the stem of the jute plant. The specific type of fibers that are commercially harvested are known as phloem fibers.

3. **Analyzing the Options**:
- **Option 1: Sieve Fibres** - These are not the correct answer as they refer to a type of cell in the phloem that helps in the transport of nutrients, not the fibers used commercially.
- **Option 2: Xylem Fibres** - These fibers are found in the xylem and are not the source of jute fibers.
- **Option 3: Pollen Fibres** - Pollen fibers are not related to jute and do not provide the commercial fibers we are looking for.
- **Option 4: Fibres of Mesocarp of Coconut** - While these fibers are useful, they are not the source of jute fibers.

4. **Conclusion**: The correct answer is that commercial jute fibers are obtained from **phloem fibers** of the jute plant.

**Final Answer**: The commercial jute fibres are obtained from phloem fibers.
