Final Answer:
VS.NET allows you to step through each line of code and trace the execution of your application in Debug Mode. Option D is the answer.
Step-by-step explanation:
Visual Studio .NET (VS.NET) provides a Debug Mode specifically designed for developers to debug and trace the execution of their applications. In Debug Mode, developers can set breakpoints, inspect variables, and step through each line of code to identify and fix issues in the application's logic. Debug Mode includes features like watches, immediate window, and call stack, enhancing the debugging capabilities.
On the other hand, Release Mode is optimized for the final deployment of the application, with optimizations that may impact the ability to debug effectively. Therefore, Debug Mode is the preferred choice when developers need to step through code and trace the execution during the development and debugging phases.
Option D is the answer.
