Final answer:
The FOUR PART TEST used by Congress to determine if a regulation can discriminate or unduly burden includes: substantial nexus, fair tax apportionment, no advantage, and fairly related.
Step-by-step explanation:
The correct answer is:
- Substantial nexus: This test requires a substantial connection between the regulation and the activity being regulated.
- Fair tax apportionment: This test ensures that the regulation does not unfairly burden certain taxpayers.
- No advantage: This test prohibits regulations that provide unjust advantages to certain parties.
- Fairly related: This test demands that the regulation is fairly related to the purpose it seeks to achieve.
These four criteria are used by Congress to determine if a regulation can discriminate or unduly burden.
