The correct answer is D. All of the above.

The Economic and Social Council (ECOSOC) is one of the five main organs of the United Nations. It is responsible for promoting international economic and social cooperation and development. ECOSOC has five regional commissions:

  • The Economic Commission for Europe (ECE) was established in 1947 to promote economic cooperation and development in Europe.
  • The Economic and Social Commission for Asia and the Pacific (ESCAP) was established in 1947 to promote economic and social development in Asia and the Pacific.
  • The Economic Commission for Latin America and the Caribbean (ECLAC) was established in 1948 to promote economic and social development in Latin America and the Caribbean.
  • The Economic Commission for Africa (ECA) was established in 1958 to promote economic and social development in Africa.
  • The Economic and Social Commission for Western Asia (ESCWA) was established in 1973 to promote economic and social development in Western Asia.

These commissions provide a forum for governments to discuss economic and social issues, and to develop and implement policies to address these issues. They also provide technical assistance to governments and other organizations.
