The question given below contains three elements. These elements may or may not have some inter linkage. Each group of elements may fit into one of these diagrams at (A), (B), (C), (D) and/or (E). You have to indicate the group of elements which correctly fits into the diagrams. Which of the following diagrams indicates the best relation between Parents, Mother and Father ?

Show answer & explanation
Concept: When a category is defined as the union of two mutually exclusive sub-categories, its Venn diagram is one enclosing shape that fully contains two separate circles for the sub-categories, and those two inner circles never touch or overlap each other.
Application: A parent is, by definition, either a mother or a father, never both, since mother and father are opposite, mutually exclusive sexes. So the diagram must show Mother and Father as two circles that share no region. At the same time, every mother and every father is a parent, so both circles must sit fully inside one larger shape labelled Parents.
Cross-check: Verify both conditions independently: enclosure (are Mother and Father entirely inside Parents?) and disjointness (do Mother and Father share any region?). Only the diagram with one large oval fully enclosing two separate, non-touching circles satisfies both at once.
Why the other diagrams do not fit:
Three circles that all overlap each other, each pair sharing a region with one common central overlap, would mean Parents, Mother and Father are only partially related to one another. But Mother and Father share no members at all, so no overlap between them should appear.
Three circles nested one fully inside the next would mean each category is a subset of the next larger one in a single chain. But neither Mother nor Father is a subset of the other; they are separate categories that both sit inside Parents, not stacked one inside the other.
Two circles nested one inside the other alongside a third, fully separate circle would mean two of the three categories are related while the third has no connection to either. But here all three categories are related to each other, since both Mother and Father sit inside Parents, so no category should stand completely apart.
