Synthetic fibres are made by human beings. Example – Rayon, nylon, etc.

Natural fiber:
Natural fibers are those which are obtained from plants and animals. They have been used by humans for thousands of years to make various products. Some common examples of natural fibers include cotton, silk, wool, jute, and hemp. These fibers are known for their strength, durability, and comfort.

Synthetic fiber:
Synthetic fibers are man-made fibers that are produced by chemical processes. They are created by combining different chemicals to form long chains of polymers. These fibers are designed to have specific properties such as strength, elasticity, and resistance to chemicals and heat. Some commonly used synthetic fibers include polyester, nylon, acrylic, and rayon.

Both of these:
The correct answer to the question is option 'B', which states that synthetic fibers are made by human beings. This means that synthetic fibers are not naturally occurring but are instead created through various chemical processes.

Explanation:
The distinction between natural and synthetic fibers lies in their origin. Natural fibers are derived from plants and animals, whereas synthetic fibers are manufactured by humans using chemical processes. Natural fibers have been used by humans for centuries, while synthetic fibers are a relatively recent development.

Natural fibers have several advantages. They are renewable and biodegradable, making them more environmentally friendly. They also have inherent properties such as breathability, moisture absorption, and softness, which make them suitable for clothing and other textile applications.

Synthetic fibers, on the other hand, have their own set of advantages. They can be engineered to have specific properties, such as strength, durability, and resistance to wrinkles and stains. They are also less expensive to produce compared to natural fibers. However, synthetic fibers are not biodegradable and can contribute to environmental pollution.

In conclusion, both natural and synthetic fibers have their own unique characteristics and applications. While natural fibers have a long history of use, synthetic fibers have become increasingly popular due to their versatility and affordability.
