a.

c.

d.

B. Implied

Explanation:

Implied powers of Congress refer to its powers not explicitly stated in the U.S. Constitution, but that are deemed necessary to carry out the nation, and that are backed up under the Section 8, Article I of the Constitution as it states:

The Congress shall have power (...) to make all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this Constitution in the government of the United States, or in any department or officer thereof.

Therefore, although the power to pass a law that increases the minimum wage is not a power explicitly stated in the Constitution (It is implied), it is part of the many ways that Congress can exercise its power to regulate commerce (...) among the several states (...) which is established in the Constitution.
