D. deciding the legality of executive orders
The list presented outlines some of the main powers and duties of the Judicial branch. This branch is accountable for evaluating laws enacted by the Congress, and determining whether acts of the other branches of the government (Legislative and Executive) are constitutional or not, therefore it has the power to decide the legality of executive orders (Option D).
A. is wrong because it is the President who can veto the laws passed by Congress. B is incorrect because it is the Congress or state legislatures the ones that can call for amending the Constitution, and C is also incorrect because the President is the one who nominates the district court judges, as well as the Supreme Court justices and the court of appeals judges.
