Attempted by 16 students.
Show answer & explanation
1. Analyze the relationship between the first two classes: All "Dogs" are "Animals", and all "Pets" are "Animals". Therefore, the circles for Dogs and Pets must be drawn completely inside the larger circle representing Animals. 2. Analyze the relationship between the subclasses: Some "Dogs" are "Pets", and some "Pets" are "Dogs" (but not all pets are dogs, e.g., cats). 3. This means the circles representing Dogs and Pets must intersect each other. 4. Option D correctly displays a large outer circle (Animals) enclosing two intersecting inner circles (Dogs and Pets). Final Answer: Option D
