Question 9 and 10 are based on the following fact situation: The State of X enacted legislation that imposed a 10 p.m. driving curfew on all persons under eighteen years of age. The purpose of the legislation was to reduce the state's automobile accident rate. The statute also provided that parents of any minors who violated the curfew were to be held directly responsible for their behavior. The statute was to go into effect in 90 days. Before the legislation became effective, a 'concerned parent' group brought suit in federal court seeking to enjoin its enforcement. In addition they sought a declaratory judgment that the regulation violated the 14th Amendment due process requirement of the United States Constitution.

Assume there existed, at the time the curfew act was enacted in the State of X, a federal curfew statute restricting the use of interstate highways by minors after midnight. The 'Concerned Parent' group should argue that:

Select one:

A. The state has no authority to regulate interstate travel.

B. Neither state nor federal power to regulate commerce includes power to prohibit travel.

C. The doctrine of preemption invalidates the state legislation.

D. Federal legislation governs if an intrastate matter affects interstate commerce.
