What does "Ginkgo" refer to in terms of its common name?

The term "Ginkgo" refers to the common name for Ginkgo biloba, which is often called the "Silver Apricot." This name arises from the tree's unique, fan-shaped leaves and its reproductive structure, which resembles a small apricot. The fleshy seeds produced by the female Ginkgo trees have a yellowish color, contributing to the "silver" descriptor in their common name.

In contrast, other options like "Golden Apricot," "Blueberry," and "Green Walnut" refer to entirely different plants that do not share characteristics with Ginkgo biloba. The distinct identity of the Ginkgo tree, particularly its historical significance and unique biological traits, makes "Silver Apricot" the most fitting common name.
