Which group of laws would likely face 'strict scrutiny' if challenged in court?

The correct answer is laws that favor one religion over others. Strict scrutiny is a high standard of judicial review used by courts to evaluate laws that potentially infringe on fundamental rights or target specific groups, particularly when it comes to issues of discrimination or the exercise of rights protected by the First Amendment.

Laws that favor one religion over others are subject to strict scrutiny because they may violate the Establishment Clause of the First Amendment, which prohibits the government from establishing an official religion or unduly favoring one religion over another. Under strict scrutiny, the government must show that the law serves a compelling state interest and is narrowly tailored to achieve that interest, meaning there are no less restrictive means to achieve the same goal.

The other options, while they do relate to important constitutional rights, either do not fall under the same level of scrutiny or pertain to interests that do not engage strict scrutiny standards. For example, limiting freedom of speech might warrant intermediate scrutiny depending on the context, and laws regulating public parks typically fall under a lower standard of review, focusing more on the government's interest in maintaining public order and safety. Taxes on luxury items are often deemed legitimate exercises of government power concerning economic regulation without engaging strict scrutiny.
