I think D is correct because starch is a complex carbohydrate, not a protein cellulose: is a polysaccharide, not a protein.

Natural rubber: polyisoprene not protein.

I think D is the correct answer.

Cellulose is a carbohydrate.

Protein is an important part of the protective layer of rubber particles.

If this is protein then we eat this?

It's not a protein. Protein is a polymer of amino acids.

The condition now commonly known as "Latex allergy" is caused by the proteins produced from the rubber tree (Hevea brasiliensis) that are still present in the products manufactured from natural rubber latex. This allergy is not only caused by the proteins, but also by the chemicals and/or residues thereof.

The Chemical makeup of Natural Rubber is a polymer of isoprene molecules, specifically cis-polyisoprene, the main constituent.

Eg: Latex is the polymer cis-1, 4-polyisoprene" with a molecular weight of 100, 000 to 1, 000, 000 daltons. Typically, a small percentage (up to 5% of dry mass) of other materials, such as proteins, fatty acids, resins, and inorganic materials (salts) are found in natural rubber.

Actually, none of the options is right, but as Rubber contains, however, small quantity of Protein, it can be chosen as an answer.

I think the answer is cellulose.

Yes, none of the above is the answer.

How the answer should be a natural rubber?
