The power of the Supreme Court to review state actions and legislation is implied by

A) the judicial review clause of Article III.
B) the supremacy clause of Article VI.
C) the Declaration of Independence.
D) the Seventh Amendment.

The supremacy clause of Article VI establishes that federal law takes precedence over state law, and the power of the Supreme Court to review state actions and legislation is implied by this clause. This is because the Court may strike down state laws that conflict with the Constitution or federal law, in accordance with the principle of federal supremacy. The other options do not provide a direct explanation for the Court's power of judicial review over state actions and legislation.
