Show answer & explanation
Correct answer: C
The question describes traditional data storage organized by customer in separate folders inside filing cabinets. This arrangement follows a hierarchy: cabinet -> customer folder -> records/documents.
A hierarchical database management system also organizes data in a tree-like parent-child structure, where each child record has a single parent. That is why the filing-cabinet example best matches the hierarchical model.
Option A is incorrect because a relational DBMS stores data in tables with rows and columns.
Option B is incorrect because a network DBMS allows records to have multiple relationship paths, which is not the simple folder hierarchy described here.
Option C is correct because hierarchical DBMS organizes data in parent-child levels, similar to customer-wise folders in a filing cabinet.
Option D is incorrect because only the hierarchical model fits the example.
Therefore, the correct answer is Option C: Hierarchical database management system.
