The correct answer is cotton.
Cotton is a natural fiber that is made from the cellulose of cotton plants. It is a soft, breathable fabric that is often used to make clothing. Cotton is also a relatively slow-burning fiber, which means that it is less likely to catch fire than other types of fabric.
Nylon is a synthetic fiber that is made from petroleum. It is a strong, durable fabric that is often used to make clothing, carpets, and other products. Nylon is a relatively fast-burning fiber, which means that it is more likely to catch fire than other types of fabric.
Rayon is a semi-synthetic fiber that is made from cellulose. It is a soft, lustrous fabric that is often used to make clothing. Rayon is a relatively slow-burning fiber, but it is not as slow-burning as cotton.
Terrycot is a blend of
cotton and polyester. It is a strong, durable fabric that is often used to make towels and other products. Terrycot is a relatively slow-burning fiber, but it is not as slow-burning as cotton.In conclusion, cotton is the least likely to catch fire of the four fibers listed.
