Option B is correct because the textbook context explicitly states that 'within democracies there can be very high degree of inequalities.' The text explains that while democracies are based on political equality where all individuals have equal weight in electing representatives, there are growing economic inequalities. A small number of ultra-rich enjoy a highly disproportionate share of wealth and incomes, while those at the bottom have very little to depend upon. The context also cites examples like South Africa and Brazil where the top 20% take away more than 60% of national income, leaving less than 3% for the bottom 20% population. Options A, C, and D are incorrect as the context shows dictatorial regimes have had slightly better economic growth records, but does not support that dictatorship is better overall or that inequalities don't exist under dictatorship.
