Final answer:
The accurate statement about the Necessary and Proper Clause is that it is the source of Congress's implied powers, allowing it to legislate beyond the specifically enumerated powers for broader governance objectives, including military actions.
Step-by-step explanation:
The statement about the Necessary and Proper Clause that is accurate is: A)It is the source of implied powers.
The Necessary and Proper Clause, found in Article I, Section 8 of the Constitution, grants Congress the ability to pass laws that are necessary and proper for carrying out its enumerated powers. This clause is often referred to as the 'elastic clause' due to its ability to stretch beyond the explicit list of powers to cover implied ones necessary for governance. This includes actions such as establishing a national bank, regulating commerce, and providing for national defense, which may not be explicitly stated but are considered essential to the operation of the federal government.
Historically, the Clause has been invoked for an array of federal actions, including those relating to military and domestic policies, helping the government to adapt and uphold responsibilities in the face of changing national circumstances.
