Why Might the Delegates to the Constitutional Convention Have Rejected

Why might the delegates to the Constitutional Convention have rejected a motion to include a bill of rights in the Constitution?

A) The delegates thought rights should be guaranteed to the states, not to individual citizens.
B) The delegates thought that the federal government was already limited to its expressed powers, so a bill of rights was unnecessary.
C) The delegates were pressed for time and considered setting up a basic governmental framework to be vastly more important.
D) A bill of rights would have required granting equal rights to women, which the delegates found to be politically unsavory.
