Which construct includes a finally block that executes after either the try or catch block completes?

• A. Try-Catch-Finally
• B. Xml
• C. Trigger
• D. Unit Testing

Answer: (A)

The key idea is that a finally block is part of an exception-handling structure that guarantees cleanup code runs no matter how the try block ends. This means the code in the finally section executes after the try completes, whether or not an exception was thrown and whether a catch handled it. The best fit is the construct that explicitly ties together try, catch, and finally. It includes a finally block designed for always-executing cleanup, such as releasing resources or closing files, even if an error occurred. For example: try { // open a file or acquire a resource } catch (Exception e) { // handle error } finally { // always execute to release the resource } Xml is a data format, not a runtime control structure with exception handling. Trigger is a database construct for reacting to events, not about guaranteeing final execution. Unit Testing is a testing practice, not a code structure that provides a finally block.
