# Which of the following is an elastomer?

$\begin{array}{1 1}(a)\;\text{nylon}&(b)\; \text{teflon}\\(c)\;\text{buna-s}&(d)\;\text{polythene}\end{array}$

The polymers that have elastic character like nuclear are called elastomers.Here out of the following options buna-s is an elastomer.Nylon,teflon & polythene does not have elastic character.
Hence (c) is the correct answer.
