B Correct answer
Explanation

DL/I databases have a maximum limit of 15 levels in their hierarchical structure. This is a fundamental architectural limitation of IMS databases. The hierarchical model organizes data in a tree structure with parent-child relationships, and 15 levels is the maximum depth allowed by the system.
