Introduction:
Man-made fibers are synthetic fibers that are chemically produced and have a wide range of applications in the textile industry.

Explanation:
Out of the given options, the first man-made fiber is rayon.

What is Rayon?
Rayon is a man-made fiber that is created from cellulosic materials such as wood pulp or cotton linters. It was first produced in the late 1800s and was initially used as a substitute for silk.

History of Rayon:
In 1884, French chemist Hilaire de Chardonnet developed the first practical process for producing rayon. He discovered that if cellulose was dissolved in a solution of copper sulfate and ammonia, it could be extruded into fibers. The resulting fiber was shiny and soft, and it quickly became known as "artificial silk."

Uses of Rayon:
Rayon has a wide range of applications in the textile industry. It can be blended with other fibers such as cotton, polyester, and nylon to create fabrics with different properties. Rayon is commonly used to make clothing, such as dresses, blouses, and shirts. It is also used to make home furnishings such as curtains and upholstery.

Advantages of Rayon:
- Rayon is soft and comfortable to wear.
- It has a good drape and can be easily dyed in a variety of colors.
- It is absorbent and breathable, making it ideal for use in hot and humid climates.

Disadvantages of Rayon:
- Rayon is not very durable and tends to shrink and wrinkle easily.
- It is not as strong as natural fibers such as cotton and wool.
- It is highly flammable and can melt when exposed to heat.

Conclusion:
In conclusion, rayon was the first man-made fiber to be produced and has since become a widely used material in the textile industry. While it has its advantages and disadvantages, it continues to be a popular choice for clothing and home furnishings.

It's not rayon as it is semi synthetic fibre so the correct answer is nylon
