The united states government is attempting to require all states reconfigure drivers’ licenses to conform to biometric standards at the federal level. this would cost states, and ultimately citizens a significant amount of money. states would likely argue that the federal government is creating an undue burden and the us government is infringing upon them

their reserved powers under the 10th Amendment

Explanation:

              The first 10th Amendments to the United States Constitution was made in the year 1791 and is known as the Bill of Rights.

The 10th amendment states that :

"The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people."

               In simple terms, the Tenth Amendment comes under the Bill of Rights and it defines the balance and distribution of powers between the states and federal government .

               The United States government is trying to reconfigure the driving license into biometric standards.  But the States are arguing that the federal government is creating undue burden and is violating the reserved powers under the 10th Amendment.

Thus the answer is

"their reserved powers under the 10th Amendment".
