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) and/or (D). You have to indicate the group of elements which correctly fits into the diagrams. Which of the following diagrams indicates the best relation between Elephants, Wolves and Animals?

Show answer & explanation
Concept: In a group-relation (Venn diagram) question, the correct diagram must encode each stated relationship exactly. A smaller circle drawn fully inside a larger circle means every member of the smaller category also belongs to the larger one (an is-a / subset relationship). Two circles drawn overlapping means the two categories can share common members. Two circles drawn separate, not touching, means no member can belong to both categories at the same time.
Application: Here every Elephant is an Animal, and every Wolf is an Animal, so both the Elephant circle and the Wolf circle must sit fully inside the larger Animals circle. At the same time, no elephant is a wolf and no wolf is an elephant, so the Elephant circle and the Wolf circle must not touch or overlap each other.
Cross-check by value against each other diagram:
A diagram of two large overlapping circles with a smaller circle nested in their shared region wrongly implies Elephants and Wolves have common members, with a further subset inside that overlap.
A diagram of three equal, independent circles with none enclosing the others wrongly treats Animals as just a third unrelated group instead of the category containing both Elephants and Wolves.
A diagram of three fully nested (concentric) circles wrongly implies one of Elephant or Wolf is itself a subset of the other.
Result: only the diagram with two separate, non-overlapping circles enclosed within one larger circle correctly shows both Elephants and Wolves as animals while keeping the two categories disjoint from each other.
