Best Answer Explained in Below-:

The Organization of the Petroleum Exporting Countries (OPEC) is an intergovernmental organization founded in 1960, primarily aimed at coordinating and unifying the petroleum policies of its member countries, with the goal of stabilizing oil markets and securing a steady supply of oil. Among the countries listed in the options, Angola is the most recent to join OPEC, having officially become a member in January 2007.

Angola's accession to OPEC was significant due to its increasing oil production capabilities and its status as one of Africa's largest oil producers; the country sought to collaborate with other oil-rich nations to influence global oil prices and secure its economic future.

Rwanda, Uganda, and Bolivia have not been associated with OPEC membership; thus, they are not the correct answers. As a member of OPEC, Angola contributes its unique market conditions and production experience, which impact both the organization and the global oil market. Therefore, the correct answer to the question is B) Angola.
