On visiting a tailoring shop, we see

When we visit a tailoring shop, we see many different types of textiles made of wool, silk, cotton, and other materials. The interesting thing we learn from seeing these fabrics is where these fibres actually come from.

Fibres are tiny, long, thin, and flexible structures that resemble small threads. Fibres are spun into yarn and then woven into the fabric to create various sorts of clothing.
Although plants and animals are the primary suppliers of fibres today, man-made fibres are also commonly used.
Although there are many different types of fibres, they can be broadly divided into two groups, which are as follows-
Natural fibres - They are the fibres which are obtained from both plants and animals, they are hair-like raw materials and can be obtained from various plants and animals. They can further be classified as plant, mineral and animal fibres. For example - cotton, and cellulose.
Synthetic fibre - Synthetic fibres are made fibres which are synthesized in laboratories from chemicals instead of directly deriving from living organisms. They are made up of a lengthy network of small units that are linked together. For example - nylon, and rayon.

Hence, the correct answer is option C.
