Final answer:
The iron triangle is a symbiotic arrangement among Congressional committees, executive agencies, and interest groups, and not related to class-action lawsuits. It is a mechanism of mutual support within the policy-making process.
Step-by-step explanation:
The statement that the iron triangle is a relationship established through repeated litigation of class-action suits is False. The iron triangle actually refers to a symbiotic relationship among Congressional committees, executive agencies, and interest groups, rather than a relationship built through litigation. This triangular relationship means that each corner of the triangle supports and benefits from the others, creating a mutually beneficial arrangement that can influence policy-making and implementation. The idea of the iron triangle has evolved over time, with some suggesting that a more open network, called an issue network, more accurately represents current political processes.
Regarding the choices presented, the correct aspect of iron triangles is (c) a symbiotic relationship among Congressional committees, executive agencies, and interest groups. This triangular arrangement allows these actors to become experts and main decision-makers in their policy area, although it makes it challenging for outsiders to influence policy decisions.
