This question can’t be answered without the passage that comes along with jt.
Answer:
D, because John Locke was the person that influenced American Founders about freedom and liberty.
I believe that this is a Subordinate clause.
1) "Because" is a subordinate conjunction.
2) "Because there was two feet of snow", can not stand on its own. It depends on the main clause, "school was cancelled to today".
I hope this helped! :)
