Let us examine the relationship:
- Furniture is the larger category.
- Table is a type of Furniture.
- Door may or may not always be considered Furniture, but in common usage (home context), it can be.
Therefore, both Table and Door are part of the Furniture set, but are otherwise distinct.
Hence, the Venn diagram that shows two small circles inside a larger one (without overlap between Table and Door) represents this best.
That is option (C). So,
\[
\boxed{\text{Answer: Option C}}
\]
