Solution

The correct option is A Buta-1,3-diene (70%) and 30% phenyl ethane (styrene)
Styrene rubber or SBR (Styrene butadiene rubber) is prepared by the copolymerization of buta - 1,3 - diene (70%) and styrene (30%). The name Buna-S is made up of Bu which indicates Buta - 1,3 - diene, na is for Sodium (Na) and S indicates Styrene.
