[amp_mcq option1=”Wool â A protein” option2=”Rayon â Modified starch” option3=”Rubber â A natural polymer” option4=”Fullerene â An allotrope of Carbon” correct=”option2″]
The correct answer is (b). Rayon is a semi-synthetic fiber made from cellulose, a natural polymer. It is not a modified starch.
Wool is a natural fiber made from the hair of sheep. It is a protein fiber.
Rubber is a natural polymer made from the sap of rubber trees. It is an elastomer, a material that can be stretched and then returns to its original shape.
Fullerene is an allotrope of carbon, meaning that it is a form of carbon with a unique atomic structure. Fullerenes are spherical or ellipsoidal molecules made up of carbon atoms arranged in a honeycomb lattice.
