    Correct Answer
    B. Hierarchicy
    Explanation
    The correct answer is "Hierarchy." Hierarchy is a method of organizing files where they are arranged in a tree-like structure, with parent and child relationships.

In a graphical representation, hierarchy is often depicted with a main root or parent node, branching out into sub-nodes or child nodes. This method is commonly used in file systems and databases to organize and manage data efficiently.

This action is irreversible, and once the recycle bin is emptied, the files cannot be recovered using normal methods.
