A Lorenz Curve Showing the Current Distribution of Pre-Tax Income

A Lorenz curve showing the current distribution of pre-tax income in Canada is not an entirely accurate depiction of Canadian income distribution because

A) Statistics Canada does not actually collect data on Canadian household income.
B) Canada's tax-and-transfer system reduces income inequality,which causes the Lorenz curve to be flatter and closer to the diagonal than the pre-tax curve.
C) the data collected on Canadian income distribution does not allow for an accurate plotting of a Lorenz curve.
D) a Lorenz curve cannot depict the distribution of income after government transfer payments have been distributed to households.
E) a Lorenz curve cannot depict the distribution of after-tax income.
