Final answer:
In regard to which group of individuals does not fall into the civil rights classification scheme, 'd) Taxpayers' is the correct answer as it is not a classification that has historically faced discrimination under civil rights law.
Step-by-step explanation:
Civil rights issues deal with the equal treatment of certain classifications of people by the government based on shared characteristics such as race, gender, and ability. In regard to the classifications that fall under civil rights protections, three of the groups listed are historically recognized in civil rights legislation and movements:
- Racial minorities
- Women
- People with disabilities
These groups have been the focus of various civil rights campaigns and legal actions to ensure their equal treatment under the law. On the other hand, the classification of 'd) Taxpayers' does not specifically fall into this classification scheme because taxpayer status is not a shared characteristic that has historically faced discrimination in a manner similar to race, gender, or disability.
