Final answer:
The Great Compromise created a bicameral legislature with equal representation in the Senate and proportional representation in the House of Representatives.
Step-by-step explanation:
The correct answer is A. Great Compromise.
The Great Compromise, also known as the Connecticut Compromise, was a solution proposed by Roger Sherman of Connecticut to break the deadlock over representation in the national legislature at the Constitutional Convention. It created a bicameral legislature in which the upper house, the Senate, had equal representation for all states, while the lower house, the House of Representatives, had representation based on population.
For example, each state, regardless of its size, would have two senators in the Senate, similar to the New Jersey Plan's proposal for equal representation. On the other hand, representation in the House of Representatives would be based on each state's population, just like the Virginia Plan's proposal for proportional representation.
