Final answer:
Violent non-state actors are similar to IGOs and MNCs in that they operate as flexible, social networks across borders. They differ in that they use violence and physical force to achieve their goals, unlike the legitimate means used by IGOs and MNCs.
Step-by-step explanation:
In the context of globalization, new violent international actors such as terrorist groups and transnational organized crime (TOC) syndicates have both similarities and differences with intergovernmental organizations (IGOs) and multinational corporations (MNCs). These violent non-state actors (NSAs) are similar in that they operate as flexible networks which often span across multiple jurisdictions, resembling the social networks of IGOs and MNCs which are also not confined to one nation. However, they are dissimilar in that these NSAs employ violence and physical force as a means to achieve their objectives, which is a significant contrast to the legitimate activities of IGOs and MNCs.
Regarding the wrong source of power for non-state actors, it is clear that d. They are formally recognized by powerful IGOs is not characteristic of such actors, as IGOs do not formally recognize violent non-state actors given their illegitimate and illegal operations.
