The correct answer is B) The percentage of people living in urban areas increased from 1790 to 1920.
Explanation:
The graph displays the changes in the percentage of urban (orange) and rural population (blue). Moreover, this graph shows how both populations changed from 1790 to 1920. About this, the general trend is a decrease in the rural population and an increase in the rural population. Indeed, in 1790 the rural population was around 95% and this decreases to 50% by 1920. On the opposite, the urban population increases as this was around 5% in 1790 and by 1920 the population is around 50%. Thus, the statement that best reflects the data is "The percentage of people living in urban areas increased from 1790 to 1920."
