To answer this question, you need to understand the programming languages used in ASP.NET development.
ASP.NET is a web development framework that allows you to build web applications using different programming languages. The correct answer is E) All of the above.
ASP.NET supports multiple programming languages, including Visual Basic (option A) and C# (option B). Both languages can be used to create ASP.NET code files.
Option C, C++, is incorrect because C++ is not typically used to create ASP.NET code files. However, it is worth noting that you can interoperate with C++ code in an ASP.NET application using certain techniques.
Option D, Both A and B, is incorrect because it only includes Visual Basic and C#. ASP.NET supports more programming languages beyond just Visual Basic and C#.
Therefore, the correct answer is E) All of the above. This option is correct because ASP.NET allows you to create code files using multiple programming languages, including Visual Basic, C#, and others.
