it's B, It demonstrated to Congress that the president's control over the use of troops must be limited. As said in, http://cwx.prenhall.com/bookbind/pubbooks/dye4/medialib/docs/warpower.htm "The War Powers Resolution, generally known as the War Powers Act, was passed by Congress over President Nixon's veto to increase congressional control over the executive branch in foreign policy matters, specifically in regard to military actions short of formally declared war. Its central provision prohibited the President from engaging in military actions for more than sixty days, unless Congress voted approval. The key Section 1541(c) reads: (c) Presidential Executive Power as Commander-in-Chief; Limitation The constitutional powers of the President as Commander-in-Chief to introduce United States Armed Forces into hostilities, or into situations where imminent involvement in hostilities is clearly indicated by the circumstances, are exercised only pursuant to (1) a declaration of war, (2) specific statutory authorization, or (3) a national emergency created by attack upon the United States, its territories or possessions, or its armed forces.
