Which JDBC object is responsible for managing database drivers?

• A. DriverManager
• B. Connection
• C. DataSource
• D. Driver

Answer: (A)

The ability to manage and select database drivers in JDBC is handled by a central registry that keeps track of all available drivers. This role is fulfilled by the DriverManager. It registers drivers when they’re loaded, and when you request a connection it asks the registered drivers which one can handle the given URL and then delegates to that driver to establish the connection. The other options serve different purposes: a Connection is the active session with a database; DataSource is a factory for obtaining connections (often with pooling and resource management); and a Driver is the specific driver implementation that speaks the database protocol.
