In option 1, the diagram shows relationships between three groups: citizens, voters, and males. However, since the diagram does not explicitly show any connections or relationships between the groups, it does not accurately represent the relationships among the three groups.
In option 2, the diagram shows two overlapping circles representing citizens and voters. There is no mention of males in this diagram, so it does not accurately illustrate the relationships among citizens, voters, and males.
In option 3, the diagram consists of three overlapping circles representing citizens, voters, and males. Since all three circles overlap, it indicates that all citizens are voters and all males are citizens. This accurately represents the relationships among citizens, voters, and males.
In option 4, the diagram shows two separate circles representing citizens and voters, but there is no mention of males or any connection between the circles. Therefore, it does not accurately illustrate the relationships among citizens, voters, and males.
Thus, option 3 is the correct answer as it accurately represents the relationships among citizens, voters, and males.
