The correct answer is A. Nylon.
Nylon is a synthetic fiber made from long chains of molecules called polyamides. It is strong, lightweight, and water-resistant. It is also resistant to fire, making it a good choice for clothing and other products that may be exposed to flames.
Polyester is another synthetic fiber made from long chains of molecules. It is similar to nylon in many ways, but it is not as resistant to fire.
Cotton is a natural fiber made from the cellulose of cotton plants. It is soft, absorbent, and comfortable to wear. However, it is not as resistant to fire as nylon or polyester.
Terylene is a synthetic fiber made from long chains of molecules called polyester. It is similar to polyester in many ways, but it is not as resistant to fire.
In conclusion, nylon is the fiber that is least prone
to catch fire. It is strong, lightweight, water-resistant, and resistant to fire.
