Final answer:
Protected grounds such as race, gender, and sexual orientation are categories safeguarded from discrimination by laws like the OHRC and the U.S. Civil Rights Act of 1964.
Step-by-step explanation:
Three examples of protected grounds according to the Ontario Human Rights Code (OHRC) would be C) Race, gender, sexual orientation.
These categories are protected under various human rights legislations, including laws enforced by the U.S. Equal Employment Opportunity Commission (EEOC), which make it illegal to discriminate against someone on the basis of these characteristics.
Protected grounds aim to prevent discrimination and encourage equality in various areas, including employment.
Furthermore, laws like the Civil Rights Act of 1964 play a significant role in protecting these grounds by outlawing discrimination in employment and encouraging integration in education and public accommodations.
The equal protection clause of the Fourteenth Amendment also provides rights to be treated equally regardless of attributes like race, gender, or sexual orientation.
