The elastic clause states that congress can:

a)set standards of weights and measures for the entire country

b)stretch the powers listed in the constitution

c)pass laws concerning treason and counterfeiting

d)change state borders

The correct answer is B. The Elastic Clause states that Congress can stretch the powers listed in the Constitution.  

Explanation:

The Elastic Clause is inserted in Article I, Section 8 of the United States Constitution.

It is called "elastic" because it precisely allows Congress flexibility or elasticity when determining which powers correspond to it and which do not. As is known, the same constitutional article speaks of the enumerated powers of Congress, which are those to which it is explicitly authorized to carry out. What the Elastic Clause does, then, is expand the capacity of action of the Congress, to all those activities necessary and appropriate for the correct execution of the enumerated powers.
