A- the president nominates Supreme Court justices, but the senate has to approve them so it is incorrect
B- congress has the ability to declare war, but the president can deploy troops, so this is the correct choice
C- the judicial branch has the power to decide if a new law is unconstitutional, so this isn’t the correct choice
D- the house and the senate can pass laws, but they still need presidential approval. The wording of this question is weird, but since it says passing and not approving, you can tell that this isn’t the correct solution
