# Which of the following statement is correct

$\begin {array} {1 1} (a)\;\text{ Alkyl resins are addition polymers} \\ (b)\;\text{ Polystyrene is thermosetting polymer} \\ (c)\;\text{ Dacron is a fiber}\\ (d)\;\text{ Natural rubber behaves as thermosetting polymer} \end {array}$

Polymer fibers are a subset of man-made fibers, which are based on synthetic chemicals (often from petrochemical sources) rather than arising from natural materials by a purely physical process. Terylene or Dacron is a fiber
Ans : (c)
