Which classes are protected from discrimination?

The correct choice includes categories that are commonly recognized in anti-discrimination laws and policies. Discrimination based on race, origin, nationality, religion, and age is often prohibited in various legal frameworks, including civil rights laws and employment statutes. These protections are put in place to ensure that individuals are not treated unfairly or unjustly due to inherent characteristics or personal beliefs.

The categories listed in the chosen option reflect fundamental aspects of human identity and experience, which have historically been the basis for systemic discrimination. Laws such as the Civil Rights Act in the United States explicitly address these areas, protecting individuals from discrimination in areas such as employment, housing, and education.

On the other hand, while some of the other options contain legitimate concerns regarding discrimination, they may not encompass the same breadth of protection recognized under widely accepted legal standards. For instance, while economic status can be a factor in discriminatory practices, it is not uniformly protected under many of the same laws like those that cover race or religion.
