Question

question 10 of 10 which developments most led to changes in the level of presidential power during the 20th century? a. presidents increasing use of military force without congressional declarations of war b. state governments demands for greater independence from the federal government c. congresss decision to override nearly every presidential veto d. the supreme courts decision that the war powers act was unconstitutional

Explanation:

The Constitution gives Congress the power to declare war, but in the 20th - century, presidents increasingly used military force without such declarations, expanding their power. State government demands for independence don't directly relate to presidential power. Congress overriding vetoes limits presidential power rather than increasing it. The Supreme - Court has not declared the War Powers Act unconstitutional.

Answer:

A. Presidents' increasing use of military force without congressional declarations of war
