Describe the International Atomic Energy Agency (IAEA).

The International Atomic Energy Agency (IAEA) is indeed an international organization that plays a crucial role in promoting the peaceful use of nuclear energy and aims to prevent the proliferation of nuclear weapons. Established in 1957, the IAEA works with its member states and multiple stakeholders to support the safe, secure, and peaceful utilization of nuclear technology.

The agency conducts inspections and verifies compliance with nuclear non-proliferation agreements, ensuring that nuclear materials are not diverted from peaceful uses to military applications. Additionally, the IAEA provides a platform for cooperation among nations to harness nuclear science for various applications, including energy generation, agriculture, and medicine, while emphasizing safety and security.

Thus, choice B accurately captures the multifaceted role of the IAEA, highlighting its commitments to both the promotion of peaceful nuclear technology and efforts to prevent nuclear weapon proliferation. This dual focus is central to the agency's mission and reflects its significance in global nuclear governance.
