Bakelite is a thermosetting polymer, meaning it undergoes irreversible chemical reactions during its curing process to form a hard, infusible, and insoluble material. Once molded and cured, Bakelite cannot be softened or reshaped by heating, making it suitable for applications requiring high heat and chemical resistance, such as electrical insulators and durable handles for cookware.
So, the correct option is (C): Bakelite.
