Congress passed the Civil Rights Act of 1964, a statute that prohibits employment discrimination based on race, color, religion, sex or national origin. Congress also established an administrative agency, the Equal Employment Opportunity Commission (the EEC) to enforce this statute. The EEC created guidelines that define terms such as "race/color discrimination" and "sex discrimination." These guidelines are an example of a. Interpretive rules because they are expanding the scope of a statute b. Legislative rules because they require businesses to act in a certain way c. Interpretive rules because they are clarifying an ambiguous statute d. Judicial rules because they will be used in litigation
