Answer:
The answer is C) Also known as the elastic clause, this clause gives Congress all the powers it needs to carry out its enumerated powers.
Step-by-step explanation:
In general, the main purpose of this "elastic" clause, is to give Congress the flexibility to get the other 17 enumerated powers achieved. Congress is limited in its power over the American people to only those powers specifically written into the Constitution, such as determine who can be a citizen, collect taxes, establish post offices, and set up a judiciary.
