Rayon is an artificial fibre Rayon is a regenerated cellulose fiber that is made from natural sources of cellulose, such as wood and related agricultural products. It has the same molecular structure as cellulose. Viscose can mean: A viscous solution of cellulose

Natural fibres are fibres that are obtained from natural resources
artificial fibres are fibres that are made chemically in factories
hence, rayon is artificial fibre that is made of chemicals ,so it's a artificial fibre

Natural fibres are fibres that are obtained from plants and animals all the options except A part because silk is obtained from silkworms, Wood is obtained from plants and cotton is obtained from fruits of cotton but rayon is chemically prepared we use wood pulp in it but we are adding chemicals also so this is why rayon is considered as man made fibre or artificial fibre but it is not a natural fibre.

The fibre we obtained from plants and animals is known as natural fibre . Rayon is not a natural fibre because it does not obtained from plants and animals it is made up of chemical or acid . so, it is a synthetic fibre.
