Final answer:
The user interface element that supports the ability to show rows of data that can be scrolled and selected is the Table element.
Step-by-step explanation:
The user interface element that supports the ability to show rows of data that can be scrolled and selected is the Table element. A table is a structured way of presenting data in rows and columns, where each cell of the table can contain different types of data, such as text or numbers.
The List element is also an option, but it typically displays a vertical list of items, where each item in the list may or may not contain additional details.
The Grid element is a more complex user interface element that is often used to display data in a grid format, similar to a spreadsheet. It allows for more advanced interactions and customization.
Therefore, the correct answer to the question is (A) Table, as it specifically supports showing rows of data that can be scrolled and selected.
