The correct answer is B) the less one earns, the less likely is to vote.
The best conclusion someone can draw from this graph is the less one earns, the less likely is to vote.
The graph shows the voter turnout in one election year and is also showing the percentage of voting versus the income of people voting. In the graphic, we see that people that earn less than $10,000 represent 50% of the participation, meanwhile, people that earn $100,000 to $149,000 represents almost 80% of the voter's participation. One interpretation could be that the wealthiest people probably are more educated and committed with their civil responsibility to participate and vote.
