Unlawful discrimination can be based on which of the following?

The correct choice emphasizes the components of unlawful discrimination within the context of various anti-discrimination laws and military regulations. Specifically, color, national origin, race, religion, and sex are categories that are widely recognized and protected from discrimination under federal law, including Title VII of the Civil Rights Act and various Equal Employment Opportunity (EEO) guidelines. These categories are critical in ensuring that individuals are treated fairly and equitably in the workplace, promoting an environment of respect regardless of inherent characteristics or beliefs.

By highlighting these specific factors, it reinforces the importance of inclusion and equality, which are foundational principles in military leadership and organizational behavior. The focus on these characteristics helps to highlight systemic issues and encourage a diverse workforce, ensuring that everyone has equal opportunities without bias or prejudice related to their identity. This understanding is vital for Airmen leaders tasked with fostering an inclusive workplace and for adhering to service policies that combat discriminatory practices.
