Select the Venn diagram that best represents the relationship between the three given groups: Engineer, Man, Married

The correct figure is the one with three circles that all overlap one another, each pair sharing a region and a common region in the centre.
Some engineers are men and some are not, so the circles for Engineer and Man overlap.
Some engineers are married and some are not, and likewise some men are married and some are not, so Married overlaps both other circles.
A married male engineer also exists, so all three circles must share a common central region. Only three mutually intersecting circles show this.
