|C) Nylon||D) Silk|
Terylene and nylon are synthetic fibres produced by a process of polymerisation. Terylene is a polyester and nylon, a poyamide.
Silk is purely a natural product obtained from silk worms.
Rayon is a man-made material which consists of purified cellulose in the form of long fibres. Cellulose occurs in the cell wall of plants. Rayon fibre is chemically identical to cotton but has a shine like silk. Since it is basically derived from a natural source (cellulose) it is called a regenerated fibre.
