Discrimination in law refers to what action?

Discrimination in law specifically refers to unfair treatment based on certain characteristics or status, which often leads to an individual being deprived of their legal rights. The aspect that highlights this definition is the notion that discrimination can result in someone not receiving their entitled federal rights, such as voting, education, or employment protections. This captures the essence of legal discrimination, emphasizing that the act is not just about a personal grievance, but about violating established laws intended to protect individuals from inequality.

The other options, while related to unjust treatment, do not encompass the broader legal context as precisely. For instance, being denied employment may be an example of discrimination, but it does not necessarily capture the legal framework that protects rights. Similar arguments can be made for the other options, which highlight personal injustices or service denials but do not directly articulate the legal implications of discrimination in relation to federal rights. Thus, the correct answer resonates with the core issue of legal protection against discriminatory actions.
