Answer:
A the president
Step-by-step explanation:
The President has several executive abilities, but declaring war is not one of them. In fact, Congress is instead the branch that is able to do this (the President has to go through Congress to make this happen). The Attorney General deals with legal decisions and does not have the power to declare war or send soldiers to a foreign country. The Supreme Court does not deal with making decisions in either of these occurrences either..
