(a) If any country gives more money to international institutions and its citizens want more respect and more power, it would not contribute to democracy at the global level. Every country and its citizens enjoy equal status whether it is a poor or a rich country. Equality is the basic principle of democracy.
(b) If any country is small or poor but its citizens are treated equally and their voice is heard with equal respect it will promote to equality and freedom of expression. If this is done at the global level, then this will definitely contribute to democracy at the global level. Because of these two facts we can say that the (b) position is nearer to democracy.
(c) The third position would also not lead to democracy at the global level because there should be no distinction between the rich nations and the poor nations. Otherwise it will not help in bringing socio-economic equality which is one of the important aspects of democracy. At the global level all the countries, whether poor or rich, should be treated at par with each other.
(d) The last (d) position would also not contribute democracy at the global level because the sizes or the geographical area of a country should not be a condition of superiority. However, in my opinion in international organizations like UN, General Assembly should become like a world parliament with representatives from each country in proportion to the population of the country further study
