Match List-I with List-II.

List-I (Polymer)	List-II (Monomer)
A. Neoprene	I. Acrylonitrile
B. Teflon	II. Chloroprene
C. Acrilan	III. Tetrafluoroethene
D. Natural rubber	IV. Isoprene

Choose the correct answer from the option given below:

We need to match each polymer with its monomer.

A. Neoprene

Neoprene is a synthetic rubber made by polymerization of chloroprene (2-chloro-1,3-butadiene).

$$\therefore$$ A $$\rightarrow$$ II (Chloroprene)

B. Teflon

Teflon (polytetrafluoroethylene, PTFE) is formed by polymerization of tetrafluoroethene ($$CF_2 = CF_2$$).

$$\therefore$$ B $$\rightarrow$$ III (Tetrafluoroethene)

C. Acrilan

Acrilan is an acrylic fiber made by polymerization of acrylonitrile ($$CH_2 = CH - CN$$).

$$\therefore$$ C $$\rightarrow$$ I (Acrylonitrile)

D. Natural rubber

Natural rubber is a polymer of isoprene (2-methyl-1,3-butadiene).

$$\therefore$$ D $$\rightarrow$$ IV (Isoprene)

The correct matching is: A-II, B-III, C-I, D-IV

Hence, the correct answer is Option A.
