D) about a quarter of Southerners had enslaved workers.
Not everyone in the South operated with slaves as their labor force. There were also smaller family farms and such. But those who did hold slaves in operating plantations held large numbers of slaves, and so the institution of slavery was a gigantic part of the Southern economy.

I believe that the English Bill of Rights influenced the American colonies by providing a model of representative government.
I don't think A is correct because at the time, those three branches of government didn't exist yet. C is also incorrect because Britain didn't want to give America any freedoms. D is incorrect because that has nothing to do with either Bill of Rights or the American governmental system.
