   A developer is evaluating two approaches for building a GUI: using a visual designer that generates code, or writing the code manually. The application requires highly custom widgets that the designer does not support. Which approach is more appropriate, and why?

   • AManual coding, because visual designers are not compatible with Python.
   • BManual coding, because the visual designer cannot generate code for custom widgets.
   • CVisual designer, because it is always faster and more efficient.
   • DVisual designer, because it eliminates the need for event-driven programming.

   • AEvent-driven programming, which makes the application run faster.
   • BClassical programming, which ensures the code is easier to debug.
   • CVisual programming, which reduces the need to write layout code manually.
   • DFunctional programming, which eliminates the need for event handlers.
