Right option is (b) Nomex

For explanation: Nomex is a highly fire-resistant meta-aramid polymer that is rigid and durable. Its monomers are m-phenylenediamine and isophthaloyl chloride. It is commonly used in firefighting equipment and in the driving apparel of racers to protect them in the case of a fire.
