Which of the following is NOT one of the six protected categories of Equal Opportunity (EO)?

The correct answer is that age is NOT one of the six protected categories typically recognized under Equal Opportunity (EO). The six protected categories usually include race, color, religion, sex, national origin, and disability. While age is a significant factor in many employment laws, such as the Age Discrimination in Employment Act (ADEA), it is not universally classified within the core protected categories listed under Equal Opportunity guidelines.

On the other hand, color, religion, and sexual orientation are indeed items covered under various EO laws, making them part of the protected categories. This distinction is important for understanding how different laws and regulations come into play regarding equal employment opportunities and protections under the law.
