What describes data that is read from left to right?

The correct answer is horizontal. This term specifically describes the orientation of data or information that is organized or presented from left to right across a page or screen. In typical spreadsheet applications or tables, for instance, the data is arranged horizontally in rows, which allows for easy reading and comparison of items lined up next to one another.

In contrast, vertical refers to data organized from top to bottom, while diagonal might imply data presented at an angle, neither of which aligns with the left-to-right reading direction. Sequential generally refers to a particular order or sequence but does not provide information on how the data is arranged spatially. This makes horizontal the most accurate choice to describe data that is read from left to right.
