To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Yes - This option is incorrect because two different .NET programming languages cannot be mixed in a single ASPX file. An ASPX file is a web page file that contains HTML markup and server-side code written in a .NET programming language such as C# or Visual Basic. While you can have multiple programming languages in a single solution or project, each ASPX file should be written in a single programming language.
Option B) No - This option is correct. Two different .NET programming languages cannot be mixed in a single ASPX file. Each ASPX file should be written in a single programming language.
Option C) Maybe - This option is incorrect because the possibility of mixing different .NET programming languages in a single ASPX file is not dependent on any conditional factors. It is simply not allowed.
Option D) None of the above - This option is incorrect because the correct answer is B, as explained above.
The correct answer is B. Two different .NET programming languages cannot be mixed in a single ASPX file. Each ASPX file should be written in a single programming language.
