This allows a wide range of third-party tools (e.g., SQL Developer, Tableau, or custom applications) to connect using established Oracle networking standards.

The incorrect options are:

New ADB-specific protocols (A):There are no proprietary, ADB-specific protocols; it uses Oracle’s existing Net Services framework.

SQL*NET only (C):While SQLNet is part of Oracle Net Services, the broader term “Oracle Net Services” encompasses all supported protocols, not just SQLNet.
