Pressure groups are best described as...

• A. Trade unions
• B. Regulators
• C. Lobbyists
• D. Advocacy groups monitoring environmental impact and sustainability practices

Answer: (D)

Pressure groups are organizations that seek to influence public policy and decision-making by applying pressure on governments, businesses, and other power holders. The description "advocacy groups monitoring environmental impact and sustainability practices" fits best because it reflects how these groups actively push for changes on a specific issue and keep watch on relevant practices to ensure accountability and policy alignment. They use campaigns, lobbying, petitions, and public campaigns to shape outcomes around their chosen concerns.

Trade unions are a type of pressure group, but the statement describes pressure groups in general as advocacy entities focused on monitoring and influencing, not just a single example. Regulators are government bodies, not pressure groups. Lobbyists are individuals or firms hired to influence policymakers, not the groups themselves.
