B. two legislatures, one with an equal number of votes for every state, and one determined by proportional representation
Explanation:
The Great Compromise, also known as the Connecticut Compromise was a decision reached between small and large states during the Constitutional Convention of 1787, where it as agreed that a bicameral legislature would be adopted. This meant that the upper house would have an equal number of votes per state and the lower house would proportionately represented based on the individual state population.
Therefore, the Great Compromise allowed for two legislatures, one with an equal number of votes for every state, and one determined by proportional representation.
