The Correct Option is C

Solution and Explanation

The figure shows the repeating unit -[CH2-C(CH3)2]n-.
This is formed by addition polymerisation of isobutylene, (CH3)2C=CH2.
The polymer is therefore named polyisobutylene (used in butyl rubber). Polyisoprene would contain a C=C in each repeat unit, and 'polyisobutane' is not a polymer name.
Answer: (3) Polyisobutylene
