What action does "overthrow" refer to?

The term "overthrow" specifically refers to the act of removing a leader or government from power, often through the use of force. This action implies a significant and often violent change in political power, typically involving a rebellion or coup d'état. Such methods can include military action or uprisings, where individuals or groups challenge and seek to dismantle an existing authority.

In contrast, the other choices describe different political actions that do not involve the use of force to remove governing bodies. Changing laws peacefully involves reform through legislation and civic engagement rather than forcible removal. Negotiating with political figures implies dialogue and consensus-building, while supporting a regime involves maintaining or reinforcing the current government's authority. Each of these contrasts with the concept of "overthrow," which centers on forceful removal rather than any peaceful or supportive means.
