Buna - S can be represented as:

Correct answer

Step-by-step solution

Buna-S is a copolymer of 1,3-butadiene and styrene. It is prepared by copolymerisation of 1,3 butadiene and styrene along with sodium. In this process peroxide is used as a catalyst at 5 ∘ C therefore the formed product is also known as cold rubber.
