Final answer:
The main UI configurable elements like forms and tiles are typically manipulated using JSON scripting or a UI builder, with the latter being a more visual tool for configuration.
Step-by-step explanation:
The main UI configurable elements typically include components such as forms, buttons, tiles, and others, which can be configured by developers or designers to suit the needs of a particular application. These configurations can often be done through various methods, including JSON scripting or using a UI builder tool. The specifics can vary depending on the technology or platform being used. For example, some web development frameworks might allow configuration through JSON scripts that define properties like size, color, and behavior of UI elements. Conversely, UI builders provide a more visual approach which can be particularly useful for those who are less comfortable with coding. In this context, option D is likely to be correct: Elements: Forms, Tiles; Configuration: UI builder.
