Final answer:
The Supreme Court upheld the university's actions in the given scenario, which corresponds to the actual case of Grutter v. Bollinger where the Court affirmed the use of race as a plus factor in university admissions to achieve student body diversity.
Step-by-step explanation:
In the case of McKinney v. University of G refers to the hypothetical case described, the United States Supreme Court upheld the University's actions, which may be related to an admissions policy or another aspect of university policy. The decision referenced would be consistent with what occurred in Grutter v. Bollinger, a real case where the Supreme Court upheld the University of Michigan Law School's use of race as a "plus factor" in admissions to achieve diversity, based on the Equal Protection Clause of the Fourteenth Amendment. Thus, the correct answer to the student's question is: A. It upheld the university's actions.
However, it is worth noting that 'McKinney v. University of G' does not align with any known Supreme Court decision and may be a typographical error or a hypothetical situation. Instead, the description provided is reminiscent of the landmark case, Grutter v. Bollinger.
Without a specific reference to an actual case named 'McKinney v. University of G,' one can only assume the information is intended to be framed within the context of Supreme Court decisions on university policies and the Equal Protection Clause, such as in Grutter v. Bollinger.
