Option B is the right answer, that the Virginia and New Jersey Plans differed mainly over whether States should send an equal number of representatives to Congress.
The Virginia Plan was a proposal by the representatives of Virginia for Bicameral Legislative Branch. This plan is significant for its performance in establishing the stage for the convention and, in particular, for the formulation of the idea of representation as according to the population. Whereas the New Jersey Plan of June 1787, was an acknowledgement to the Virginia Plan, since the Virginia plan called for Bicameral in Congress and the supporters of the New Jersey plan demanded the Unicameral arrangement from the article of Confederation.
Although the New Jersey Plan was refused as a basis for the new Constitution, yet some elements were taken from it. Therefore the Virginia plan was adopted in the formation of the new constitution. And the most extensive use of these plans was used by the Connecticut Compromise ( which in part set the legislative structure and representation that each state would have), that placed a Bicameral authority by the House of Representatives of the United States, elected by the American people, and that the Senate provided equality of votes to each state as the New Jersey Plan requested.

As manifest destiny and reconstruction began spreading, the government did not focus on rebuilding its navy and a large part of the navy that remained had to focus on things like helping merchants or doing civilian runs in order to be sustained.
