Regulation consists of government-imposed requirements to achieve purposes, such as cleaner water and safer workplaces.

• A. Industry self-regulation without government involvement.
• B. Voluntary guidelines issued by trade associations.
• C. A tax policy to raise revenue.
• D. Government-imposed requirements to achieve purposes, such as cleaner water and safer workplaces.

Answer: (B)

Regulation means rules that the government imposes and enforces to achieve public goals, like cleaner water and safer workplaces. The description that fits this idea best is the one that states government-imposed requirements aimed at those outcomes. That’s why it is the correct match. Other ideas describe nonbinding or non-regulatory approaches: industry self-regulation without government involvement, voluntary guidelines issued by trade groups, or using a tax policy for revenue, none of which impose mandatory standards or duties backed by government authority.
