Identify the chain initiation step of the polymerisation of ethene in the presence of benzoyl peroxide initiator, from the following?

A. C<sub>6</sub>H<sub>5</sub> + C<sub>2</sub>H<sub>4</sub> = C<sub>6</sub>H<sub>5</sub>-CH<sub>2</sub>-CH<sub>2</sub>
B. C<sub>6</sub>H<sub>5</sub>-CH<sub>2</sub>-CH<sub>2</sub> + C<sub>2</sub>H<sub>4</sub> = C<sub>6</sub>H<sub>5</sub>-CH<sub>2</sub>-CH<sub>2</sub>-CH<sub>2</sub>-CH<sub>2</sub>
C. C<sub>6</sub>H<sub>5</sub>-CH<sub>2</sub>-CH<sub>2</sub>-CH<sub>2</sub>-CH<sub>2</sub> = C<sub>6</sub>H<sub>5</sub>-(-CH<sub>2</sub>-CH<sub>2</sub>-)<sub>n</sub>-CH<sub>2</sub>
D. C<sub>6</sub>H<sub>5</sub>-(-CH<sub>2</sub>-CH<sub>2</sub>-)<sub>n</sub>-CH<sub>2</sub> + C<sub>6</sub>H<sub>5</sub>-(-CH<sub>2</sub>-CH<sub>2</sub>-)<sub>n</sub>-CH<sub>2</sub> = C<sub>6</sub>H<sub>5</sub>-(-CH<sub>2</sub>-CH<sub>2</sub>-)<sub>n</sub>-C<sub>6</sub>H<sub>5</sub>
Answer» B. C<sub>6</sub>H<sub>5</sub>-CH<sub>2</sub>-CH<sub>2</sub> + C<sub>2</sub>H<sub>4</sub> = C<sub>6</sub>H<sub>5</sub>-CH<sub>2</sub>-CH<sub>2</sub>-CH<sub>2</sub>-CH<sub>2</sub>
