Which natural polymer makes up paper? starch, nylon, wool, or rubber

Answer

Option A = Starch  

Explanation

Starch or amylum is a polymeric carbohydrate consisting of a large number of glucose units joined by glycosidic bonds.  It is the most common carbohydrate in human diets and is contained in large amounts in staple foods like potatoes, wheat, maize (corn), rice, and cassava. The biggest industrial non-food use of starch is as an adhesive in the paper making process.  

Nylon is widely used to make jackets, sports bags, tents, parachutes and bathing suits.

Wool has been used for blankets, horse rugs, saddle cloths, carpeting, insulation and upholstery.

The largest consumers of rubber are tires and tubes. Other significant uses of rubber are hoses, belts, matting, flooring, medical gloves and much more.

I believe the appropriate pair is O and S, Periodic table represents arrangements of elements ordered by their atomic number,physical and chemical properties. Both sulfur and oxygen are in the same group of the periodic table (group 6), they have a valency of 2, This means they have a greater similarity in chemical and physical properties.
