Concept: In a Venn diagram for three related classes, the shape of the circles must match the logical relation between them: two classes that share some members but where neither contains the other are drawn as intersecting circles; a class that is entirely a subset of another is drawn as one circle fully nested inside the other; and a class every member of which belongs to a broader category is drawn entirely inside a single larger circle standing for that category.

Application: Here, some boys are infants and some infants are boys, but neither group contains the other, so Boys and Infants must be drawn as two circles that overlap in a genuine shared region. At the same time, every boy and every infant is a human, so both of those overlapping circles must be drawn completely inside one larger circle standing for Humans.

Cross-check: This rules out treating any of the three classes as fully separate from the rest (that would deny the existing overlap between boys and infants), and it rules out nesting all three strictly one inside the next like rings of a target (that would wrongly require every infant to be a boy, and every boy in turn to be nothing more than a subset of humans with no overlap of its own). Only a diagram with two overlapping inner circles fully enclosed by one outer circle satisfies both conditions at once.

Result: The diagram with two overlapping circles (for Boys and Infants) fully enclosed within one larger circle (for Humans) is the correct representation, as shown below.
