Question

federal mandates often:
require states to comply with federal regulations
eliminate state regulations
increase state autonomy
decrease federal influence over states

Explanation:

Federal mandates are directives from the federal government. Their primary role is to make states follow federal regulations (e.g., for policies like environmental or civil rights). Eliminating state regulations is not their main goal (states still have their own regulatory spaces). Increasing state autonomy would go against the idea of a federal mandate (which is a federal directive), and decreasing federal influence is also incorrect as mandates assert federal influence.

Answer:

A. Require states to comply with federal regulations
