Which plan proposed a unicameral legislature where all states would have equal votes?

The New Jersey Plan is the correct answer as it proposed a unicameral legislature in which each state would have an equal vote, regardless of its population size. This plan was developed in response to the Virginia Plan, which favored larger states by advocating for a bicameral legislature based on population. The New Jersey Plan aimed to ensure that smaller states had equal representation, addressing concerns that their interests could be overshadowed by those of larger states.

During the Constitutional Convention, the New Jersey Plan emphasized the importance of maintaining a government structure that protected the rights and interests of smaller states, leading to significant debates about representation. Ultimately, the Connecticut Compromise, also known as the Great Compromise, resulted in a bicameral legislature with both equal representation for states in the Senate and representation based on population in the House of Representatives.
