Which of the following polymers can be formed by using the following monomer unit?

Which of the following is monomer of the given polymer?

Which of the following statements is not true about low density polythene?

Natural rubber or raw rubber consists of basic material latex which is a dispersion of isoprene. During the treatment, this isoprene forms a high molecular weight polymer of isoprene. Natural rubber can be obtained from five hundred different species of plants.
Consider the following properties of rubber,
(i) Tensile strength of vulcanized rubber is almost ten times more than raw rubber.
(ii) The elasticity of the raw rubber is very high.
Choose the correct option.
