To support concurrent access from multiple users of a shared database, the LAN modules of a DBMS add all of the above features: concurrent access controls, extra security features, and query or transaction queuing management. Concurrent access controls ensure that multiple users accessing the same data do so in a controlled manner to prevent data inconsistencies. Extra security features such as authentication and encryption are added to protect the database from unauthorized access. Query or transaction queuing management enables multiple transactions to be queued and processed in an orderly fashion to prevent conflicts and ensure data integrity. Therefore, the best choice is D.
