Select the Venn diagram description that best illustrates the relationship between the following classes:
Potatoes, Vegetables, Grapes

Potatoes are a type of vegetable, so the class 'Potatoes' is entirely contained within the class 'Vegetables'. Grapes, on the other hand, are fruit and completely separate from the class of vegetables. Therefore, this relationship is best shown by one circle completely inside another, with a third circle entirely separate.
