Quizplus · Accepted Answer

The root node is the top-most node in a tree data structure, and it has child nodes that branch off from it. Therefore, choice A (child nodes, or children) is the best choice since it accurately describes the relationship between the root and its subsequent nodes. Choice B (parent nodes, or parents) is incorrect because the root node does not have any parent nodes above it. Choices C (binary nodes) and D (subnodes) are not accurate descriptions of the relationship between the root node and its children.
