Concept:
The Group of 15 (G-15) is a grouping of developing countries from Asia, Africa, and Latin America formed in 1989 to foster cooperation and provide input to other international forums such as the G-7.
Explanation:
The founding and later members of the G-15 include countries such as Algeria, Argentina, Brazil, Chile, Egypt, India, Indonesia, Iran, Jamaica, Kenya, Malaysia, Mexico, Nigeria, Senegal, Sri Lanka, Venezuela, and Zimbabwe. Mexico, Brazil, and Malaysia are all part of this list, so options A, B, and C are genuine G-15 members. Bolivia has never been part of the G-15 grouping, which is why it stands out as the odd one here.
Final Answer:
Bolivia is not a member of the Group 15 developing countries, so option D is the answer.
