Question

how does the united nations aim to achieve its purpose of promoting international cooperation? by establishing military alliances by imposing sanctions on member nations through diplomacy and negotiation

Explanation:

The United Nations promotes international cooperation mainly through diplomacy and negotiation. Military alliances are more associated with entities like NATO, and the UN does not impose sanctions on member nations as a primary way to promote cooperation (sanctions are for addressing violations, not promoting cooperation). So the correct option is the one about diplomacy and negotiation.

Answer:

C. through diplomacy and negotiation (assuming the third option is labeled C; if the options are unlabeled by identifier, the third option "through diplomacy and negotiation")
