Answer:
Clause 18 - NECESSARY AND PROPER CLAUSE
Step-by-step explanation:
Section 08, article 1 of the United states constitution contains eighteen clauses, the last being the Necessary and Proper Clause, sometimes called the “coefficient” or “elastic” clause.
The third president of the United States of America, Thomas Jefferson, talked about the necessary and proper clause in a letter he wrote the U.S. attorney for the District of New York, Edward Livingston in 1800. President Jefferson talked about the endless expansion of the national powers through clause 18 and that was done.
