Detailed Solution

The above statement is false.
Silk is a natural and animal fibre as it is obtained from moth bombyx Mori.
There are two classes of fibres: synthetic and natural fibres. Natural fibres in turn are of two types: plant obtained and animal obtained. Natural fibres are those which are obtained from plant products or plant parts such as stems, roots and fruits. Cotton is obtained from cotton balls and extracted as fibres. Silk is obtained from moth cocoons. Cocoons are produced at a particular stage of the life cycle of a moth or silkworm. Wool is obtained from animals such as goats and sheep. Stem fibres are flax, hemp and jute. Jute is also obtained from coconut husk or coir.
The correct statement would be, silk fibre is obtained from the silk moth.
