Ijust need someone to explain what this question i am confused. just tell me and i can answer it probably.

what is the consensus (majority) on the proposed law with all ten votes counted?

It's just asking you what group wins the majority (aka most of the votes) on a law, out of 10 votes.

for example, say you have a group voting on whether or not a club should get shirts made. 6 people say YES SHIRTS and 4 people say NO THAT IDEA SUCKS.

the YES SHIRTS group won the vote by a margin of 2, because 2 more people voted for shirts than the amount of people who think shirts suck. it's asking you what most of the group in your question agreed on.

The right answer here is D - the magna carta was designed to assert the rights of nobles, as well as their obligations to those below them. Specifically, a promise from the King to not mistreat his people, in accordance with feudal law. Freedom of speech is not mentioned at any point.
