The epidermal fibers of economic importance belong to
(a) Cotton
(b) Flax
(c) Hemp
(d) Coir

Options

A. Cotton
B. Flax
C. Hemp
D. Coir

Answer

To determine which of the options given corresponds to the epidermal fibers of economic importance, we can analyze each option step by step:

1. **Understanding Epidermal Fibers**: Epidermal fibers are fibers that are derived from the outer layer of plants. They are often used in various industries due to their strength and durability.

2. **Analyzing Option A - Cotton**: Cotton comes from the genus Gossypium. The fibers are actually fine epidermal hairs that grow on the seeds of the cotton plant. These fibers are harvested and processed to produce cotton fabric, which is a significant economic product.

3. **Analyzing Option B - Flax**: Flax fibers are derived from the stem of the flax plant (Linum usitatissimum). While flax is economically important, the fibers are not classified as epidermal fibers; they are bast fibers.

4. **Analyzing Option C - Hemp**: Hemp fibers come from the stalk of the hemp plant (Cannabis sativa). Similar to flax, hemp fibers are also bast fibers and not epidermal fibers.

5. **Analyzing Option D - Coir**: Coir is derived from the outer husk of coconuts. It is a fibrous material but is not classified as an epidermal fiber; it is a hard fiber.

6. **Conclusion**: Based on the analysis, the only option that corresponds to epidermal fibers of economic importance is **Option A - Cotton**.

Final Answer: (a) Cotton
