The Patient Protection & Affordable Care Act Was Challenged in a Lawsuit

The Patient Protection & Affordable Care Act was challenged in a lawsuit alleging that the federal government exceeded its authority under the constitution by requiring that people buy health insurance. The case went to the U.S. Supreme Court, which ruled:

A) striking down the law, on the basis that the federal government had violated the commerce clause
B) striking down the law, on the grounds that nothing in the Constitution authorized the law
C) upholding the law as valid, on the grounds that it did not violate the commerce clause
D) upholding the law as valid, on the grounds that it constituted a tax on the lack of health insurance
