Why Were the Ratification Debates in New York and Virginia

Why were the ratification debates in New York and Virginia critical to the success of the Constitution?

A) Even though the Constitution had already taken effect after the ninth state approved it, the federal union's chances of survival were in jeopardy without ratification from large states like New York and Virginia.
B) Since only seven states had ratified the Constitution before these states voted, their ratifications were necessary to reach the nine states required for the Constitution to go into effect.
C) New York and Virginia were two of the most strongly Federalist states, and their ratifications would silence remaining Anti-Federalist opposition.
D) Neither state had sent delegates to the Constitutional Convention, making their support for the Constitution uncertain.
