Final answer:
The Better Business Bureau and the Federal Trade Commission provide free dispute resolution services. The International Criminal Court does not offer dispute resolution for individuals but prosecutes severe international crimes. The International Court of Justice resolves disputes between countries rather than being a regional IGO.
Step-by-step explanation:
The centers that provide free dispute resolution services among the options given are the Better Business Bureau (BBB) and the Federal Trade Commission (FTC). The Small Claims Court is not free since it charges a filing fee, though it is an affordable option for resolving small civil disputes. The International Criminal Court (ICC) does not provide dispute resolution services for individuals; rather, it prosecutes individuals for severe international crimes like war crimes and genocide.
When considering international legal adjudication, the International Court of Justice (ICJ) hears cases involving disputes between countries. It is important to differentiate this from the ICC. Other international organizations that handle disputes between member states include the European Union and the World Trade Organization.
It should be noted that the International Court of Justice (ICJ) is not a regional intergovernmental organization (IGO) like the European Union (EU) or the North Atlantic Treaty Organization (NATO). Rather, it is one of the principal organs of the United Nations tasked with settling legal disputes submitted by states and providing advisory opinions on international questions referred to it by the UN.
