Which of the following actions is NOT protected under the human rights code?

Refusal of service based on appearance is typically not protected under the human rights code because appearance does not fall under the categories that are legally protected against discrimination. The human rights code focuses on specific characteristics such as race, age, religion, gender, marital status, and disability. While it is important to promote fairness and equality in service provision, refusal based solely on subjective views of a person's appearance does not usually constitute a violation of these established protections.

On the other hand, the refusal of service based on age, religion, and marital status does violate the principles established under human rights protection since they are recognized as grounds for discrimination. These categories are specifically outlined in legislation intended to safeguard individuals from unfair treatment, ensuring equal access to services regardless of these inherent characteristics. Thus, the correct response identifies a scenario that does not align with the definitions of discrimination protected by the human rights code.
