Which federal law is designed to prohibit sex-based discrimination in education, including athletics?

• A. IDEA Act
• B. National standards for Physical Education
• C. Title IX legislation
• D. ADA

Answer: (C)

Title IX is a federal civil rights law that prohibits sex-based discrimination in education programs and activities that receive federal funds, including athletics. It guarantees equal opportunities for participation, scholarships, facilities, coaching, and other aspects of sport, applying to both K–12 and higher education. This is why it best fits the description in the question: it specifically targets sex discrimination in education and athletics. Other options address different areas—IDEA focuses on students with disabilities, ADA covers disability rights broadly, and national standards for physical education are guidelines rather than a federal law.
