Question

Quizplus · Accepted Answer

In a tree structure, each node (or item) can have multiple children but only one parent, except for the root node, which has no parent. This allows the tree to branch out. Choices A, C, and D are incorrect because, in a tree, not all items have both a distinct predecessor and successor (especially leaf nodes and the root), items cannot have multiple parents (this would create a graph with cycles, not a tree), and the root node does not have any parents, respectively.
