Select the Venn diagram that best represents the given set of classes.
Animals, Mammals, Deer

- AA diagram showing three concentric circles.
- BA diagram showing two intersecting circles inside a larger circle.
- CA diagram showing three completely separate circles.
- DA diagram showing two separate circles inside a larger circle.
Solution & Step-by-step Explanation
Let us look at the relationship between the three given groups:
All Deer are Mammals.
All Mammals are Animals.
This means Deer is a complete subset of Mammals, and Mammals is a complete subset of Animals. This relationship is represented by three concentric circles containing each other sequentially. Thus, option A is correct.
All Deer are Mammals.
All Mammals are Animals.
This means Deer is a complete subset of Mammals, and Mammals is a complete subset of Animals. This relationship is represented by three concentric circles containing each other sequentially. Thus, option A is correct.
