Which of the following diagrams shows the correct relationship among the terms : Entrepreneurs, Married, Women ?
A Venn diagram shows how classes relate: a circle inside another means one class is wholly contained in the other, separate circles mean no common members, and overlapping circles mean the classes share some members.
Entrepreneurs, married persons and women are three independent classes. Some entrepreneurs are married, some are women, some women are married, and some persons are married women entrepreneurs, while each class also has members outside the other two. All three classes therefore overlap each other with a common central region, which is the diagram of three mutually intersecting circles.
Concentric circles would make one class wholly contain another, a chain of circles would leave entrepreneurs and women with no overlap, and a separate circle would wrongly make one class have nothing in common with the others.
The diagram of three mutually overlapping circles option is correct.
