Prevents discrimination on race, gender, sex and affiliation

• A. Civil Rights Act
• B. Equal Employment Opportunity Act
• C. Americans with Disabilities Act
• D. Title IX

Answer: (A)

The key idea is recognizing which law broadly prohibits discrimination across multiple protected characteristics, including race and sex, and protects individuals by their affiliation with a protected class. The Civil Rights Act of 1964 establishes sweeping protections against discrimination based on race, color, religion, sex, or national origin in many areas of public life, including employment and public accommodations. This makes it the best fit for prohibiting discrimination on race, gender/sex, and affiliation, because it covers these core protected characteristics in a wide range of contexts. The other laws focus on narrower areas—equal employment opportunities in employment settings, disability status, or sex discrimination in education and federally funded programs—whereas the Civil Rights Act provides the broad, foundational protections that match the scope described in the question.
