Article iii of the constitution gives congress the power to create a system of federal courts, other than the supreme court, known
a. superior courts.
b. inferior courts.
c. original courts.
d. appellate courts.

The correct answer should be B. inferior courts.
The Supreme Court and inferior courts are all federal courts. Superior courts are found mostly in Great Britain, but in America are types of appellate courts, which means A and D are incorrect. There is no such thing as an original court, which is why C is also not true.
