Which of the following Venn diagrams best represents the relationship between tables, chairs and lamps?

This question requires identifying the Venn diagram that accurately depicts the relationship between three distinct items: tables, chairs, and lamps.
Consider the nature of each item:
In this context, there is no inherent overlap between these three categories. A table is not a chair, nor is it a lamp. Similarly, a chair is not a table or a lamp, and a lamp is not a table or a chair.
Venn diagrams visually represent relationships between sets. Non-overlapping circles in a Venn diagram signify that the sets have no common elements.
Since tables, chairs, and lamps are distinct categories:
The correct Venn diagram must therefore show three distinct circles that do not intersect or overlap in any way.
The Venn diagram illustrating three mutually exclusive sets, represented by three separate circles, best fits the relationship between tables, chairs, and lamps.
