Who is eligible to become a member of the United Nations?

Membership in the United Nations is open to any peace-loving state that accepts the obligations outlined in the UN Charter. This principle is rooted in the foundational goals of the UN, which include promoting peace, security, international cooperation, and adherence to human rights. By accepting the obligations of the UN Charter, a state commits to upholding these values, making it eligible for membership regardless of its economic development, form of government, or financial contributions to the organization.

The other options are not correct because they impose unnecessary restrictions. For instance, limiting membership to only developed countries excludes many states that may seek to promote peace and security but do not have high levels of development. Similarly, not all member states need to have a democratic government, as the UN's focus is on peace-loving states rather than any specific political system. Financial contributions, while important for the functioning of the UN, do not determine a state's eligibility for membership. Thus, the focus on peace and a commitment to the UN Charter stands as the defining criterion for membership.
