Although the National Constitution Seems to Limit Federal Power by Its

Although the national Constitution seems to limit federal power by its suggestion that any powers not explicitly given to the national government were denied it, the framers nonetheless gave the national government a broad grant of power through:

A) the principle of judicial review, which gave the judicial branch the final word in interpretation over the Constitution.
B) the necessary and proper clause, which asserted that Congress could pass any law it deemed needed to carry out its enumerated powers.
C) the reserved powers clause, which gave the federal government all powers not explicitly given to states.
D) giving the president enough powers to ensure that "energy in the executive" could overcome problems created by the separation of powers.
