A Correct answer
Explanation

Natural rubber is a polymer of isoprene (2-methyl-1,3-butadiene). The polymerization of isoprene molecules forms polyisoprene, which is the chemical composition of natural rubber obtained from rubber trees. The other options are different synthetic polymers - polyethylene is from ethylene, neoprene is chloroprene rubber, and monoprene is not a standard polymer.
