The solution requires us to understand the relationships between the groups of words: Dogs, Pets, and Cats. Let's break this down:
- Dogs: This is a specific type of pet.
- Cats: Another specific type of pet.
- Pets: A broader category that includes dogs, cats, and possibly other animals.
Given these relationships, we need to find a diagram that accurately represents the subset and superset relationships between these groups:
- Both Dogs and Cats are Pets, so they should be shown within a larger set representing Pets.
- Dogs and Cats are separate entities, meaning they should not overlap directly with each other.
After analyzing the given options:
Option A correctly depicts these relationships:
- The largest circle represents Pets.
- Within this large circle, two smaller circles represent Dogs and Cats, indicating that both are subsets of Pets.
- The two small circles do not overlap with each other, showing that Dogs and Cats are distinct within the category of Pets.
Therefore, the diagram in Option A is the correct representation for the groups of words: Dogs, Pets, Cats.
