The correct option is C 1950 to 2000.
If we consider all democracies and
all dictatorships for the fifty years between
1950 and 2000, dictatorships have a slightly
higher rate of economic growth. The
inability of democracy to achieve higher
economic development is a serious concern. But
this alone cannot be a reason to reject
democracy. We all know economic growth is dependant upon various factors like the country's population size, global situation, etc.
