The correct answer is: D. Hierarchical database
A hierarchical database is a database model in which data is organized in a tree-like structure, with each record having one parent record and zero or more child records. This model resembles the hierarchical model in many respects, including the way that data is organized and accessed.
A network database is a database model in which data is organized in a network of records, with each record having one or more parent records and one or more child records. This model is different from the hierarchical model in that it allows for multiple parent records for each child record.
A relational database is a database model in which data is organized in tables, with each table containing a set of related records. This model is different from the hierarchical model in that it does not have a hierarchical structure.
A distributed database is a database that is stored on multiple computers, with each computer storing a subset of the data. This model is different from the hierarchical model in that it is not stored on a single computer.
None of the above is a correct answer.
