Separate electorates was a "poison that has entered the body politic of our country". Identify the speaker?

Vallabhbhai Patel

The correct answer is Option (4) → Vallabhbhai Patel

Partition had made nationalists fervently opposed to the idea of separate electorates. They were haunted by the fear of continued civil war, riots and violence. Separate electorates was a "poison that has entered the body politic of our country", declared Sardar Patel. It was a demand that had turned one community against another, divided the nation, caused bloodshed, and led to the tragic partition of the country. "Do you want peace in this land? If so do away with it (separate electorates)," urged Patel.

So, the correct option is [4].
