Which organization filed suit challenging CPPA?

• A. The American Civil Liberties Union
• B. The National Center for Missing & Exploited Children
• C. The Free Speech Coalition
• D. The Electronic Frontier Foundation

Answer: (C)

The key idea is understanding who would challenge a regulation that could limit what people can say or show. The Free Speech Coalition represents producers and distributors of adult content, and groups like this routinely sue when rules threaten free expression or impose burdens that would curb lawful speech. Their lawsuit against CPPA would be grounded in First Amendment concerns, arguing that the act’s provisions could chill or restrict the ability to publish or distribute content and impose onerous compliance on the industry. The other organizations listed focus on different angles—civil liberties in general, digital rights, or child-protection work—and aren’t the ones who filed this particular challenge, making the Free Speech Coalition the best answer.
