The correct answer is A. isoprene.
Natural rubber is a polymer of isoprene, a five-carbon hydrocarbon. It is produced by the rubber tree, Hevea brasiliensis. The rubber tree is a tropical plant that is native to the Amazon rainforest. The rubber is extracted from the tree’s sap, which is a milky white liquid. The sap is collected and then processed to remove impurities. The resulting rubber is a white, rubbery material.
