Analyzing the Relationship Between the Sets

To find the correct Venn diagram, we need to understand the relationship between the three categories: Lions, Elephants, and Animals.

1. Relationship between Lions and Animals: All lions are animals. This means the circle representing "Lions" must be completely inside the circle representing "Animals".
2. Relationship between Elephants and Animals: All elephants are also animals. This means the circle representing "Elephants" must also be completely inside the circle representing "Animals".
3. Relationship between Lions and Elephants: A lion cannot be an elephant, and vice versa. The two categories are completely separate. This means the "Lions" circle and the "Elephants" circle must not touch or overlap.

Conclusion

The correct diagram must show one large circle ("Animals") that contains two smaller, non-overlapping circles ("Lions" and "Elephants").

Looking at the options, Diagram (A) is the only one that correctly represents this relationship.
