Answer: A) America's declaration of war against Japan in 1941.
Explanation: Japan attacked the American navy at Pearl Harbor. By declaring war, the USA defended itself (and all the states and their citizens) against further attacks.
The best example of our government "providing for the common defence" is America's declaration of war against Japan in 1941. When the "founding fathers" spoke of common defence, they were referring to the nation's ability to defend itself in a unified military reaction to foreign or domestic aggression.
