The correct answer is option 1 - Cotton. Cotton is the most widely used material in the textile industry in India. Cotton is a natural fiber obtained from cotton plants and has various qualities that make it suitable for textile production. It is soft, breathable, and comfortable to wear, making it a popular choice for making garments, beddings, and home textiles. Cotton fabric also absorbs moisture well, making it suitable for hot and humid climates. Additionally, cotton is easily dyed and can be blended with other fibers to enhance its properties. Wool (option 2) is primarily used for making warm clothing and blankets, while synthetic fibers (option 3) like polyester and nylon are used for their durability and versatility. Jute (option 4) is commonly used for making sacks and bags, but it is not as extensively used in the textile industry as cotton.
