B.Polysaccharide
C.Polythene
D.Polyvinyl chloride

Answer 1

Hint: Artificial silk is the synthetic fibre which resembles silk, but comparatively costs less than the original silk. Artificial silk is also called as rayon which is made up of bamboo viscose it is also called as bamboo silk.

Complete answer:
Artificial silk or rayon is made up of cellulose, which is obtained from cotton or wood pulp the cellulose is made to dissolve in a substance called alkaline carbon disulphide to make a thick liquid. This is then made to flow from the tiny holes into a bath of acid. It then reforms as a fibre and then in turn can be spun into yarn.
Artificial silk is invented by Hilaire de Chardonnet, a French engineer and industrialist. He called his first invented artificial silk “Chardonnet silk”. He worked with Louis Pasteur to eradicate the destruction on French silkworms.
Coming to the question artificial silk is a synthetic which is manufactured from cellulose fibre. Cellulose is a common example of polysaccharides. Thus, artificial silk is synthetic from polysaccharides.

Hence, the right answer is polysaccharide

Note: this is pretty much the information about the artificial silk. After knowing about the information above we come to an idea that questions are framed from different angles, we just need to be careful and should have known the information during reading. Focus study is the key. Hence going through each and every point makes it easy to grasp and keep things in mind and now getting confused during examination. Hence when we study about certain topics we need to be familiar with everything associated with it including examples. Multiple choice is all about testing the knowledge about the subject. More like testing how well we know the concept.
