Identify the Diagram that best represent the relationship among Classes given below:

Animal, Land Animal, Sea Animal

The correct answer is Option 4: 

• Animal is the larger group.
• Land Animal and Sea Animal are two separate categories within Animals.
• A land animal cannot be a sea animal in this classification, so the two groups do not overlap.

Therefore, the correct diagram should show:

• One large circle for Animals
• Two separate small circles inside it for Land Animals and Sea Animals
