Group of Natural fibers are :

Question

Accepted Answer

Option 3, which includes Cotton, Linen, Silk, and Wool, is the correct answer because all these materials are natural fibers. Natural fibers are derived from plants, animals, or mineral sources and are known for their biodegradability and sustainability.

1. **Cotton**: This is a natural fiber obtained from the cotton plant. It is widely used in textiles due to its softness, breathability, and absorbency.

2. **Linen**: Linen is made from the fibers of the flax plant. It is valued for its strength, durability, and ability to keep cool in warm weather.

3. **Silk**: Silk is a natural protein fiber produced by silkworms. It is renowned for its smooth texture, luster, and luxurious feel.

4. **Wool**: Wool is obtained from the fleece of sheep and other animals. It is known for its warmth, elasticity, and moisture-wicking properties.

Now, let's explain why the other options are incorrect:

1. **Option 1: Orlon, Asbestos, Cotton, Dacron**
   - Orlon and Dacron are synthetic fibers, not natural. Orlon is a type of acrylic fiber, and Dacron is a type of polyester. Asbestos, while a natural mineral fiber, is not typically classified with textile fibers due to its health hazards.

2. **Option 2: Cotton, Rayon, Silk, Nylon**
   - Rayon and Nylon are not natural fibers. Rayon is a semi-synthetic fiber made from regenerated cellulose, and Nylon is a fully synthetic fiber made from petrochemicals.

3. **Option 4: Linen, Polyester, Silk, Cotton**
   - Polyester is a synthetic fiber made from petrochemicals, which disqualifies this option as a group of natural fibers.

Thus, Option 3 is the only choice that consists entirely of natural fibers, making it the correct answer.
