Which of these is a power that is the responsibility of only the national government?
a) foreign policy
b) taxation of citizens
c) promoting public health
d) providing for public safety

The only power that belongs exclusively to the national government is foreign policy. Only the federal government has the right to enter into treaties with foreign countries.

The only power that is the responsibility of only the national government is the foreign policy.
