Final answer:
VS.NET allows you to create a portable EXE file in Release Mode, which optimizes the code for performance and produces a smaller executable file.
Correct option is [D] Release Mode
Step-by-step explanation:
VS.NET allows you to create a portable EXE file in Release Mode. When you build an application in Release Mode, the compiler optimizes the code for performance and produces a smaller executable file.
On the other hand, in Debug Mode, the compiler adds additional code for debugging purposes, which can make the executable larger and slower. Therefore, it is recommended to choose Release Mode when you want to create a portable EXE file in VS.NET.
For example, if you have developed a Windows Forms application in Visual Studio and you want to distribute it as an EXE file that can be run on other computers without the need for installation, you would select Release Mode to build the portable EXE file.
