If you look at that full line from the Mayflower Compact, the colonists are discussing that they are forming a "Civil Body politic" and will "enact and frame" laws for the colony, and they confirm that they will follow the laws in "all due submission and obedience." So, B seems like the best answer here because this line from the Mayflower Compact concerns the signers following the laws they promise to make for the colony's benefit.
