Which of the following indicates the establishment of a horizontal line in data arrangement?

The establishment of a horizontal line in data arrangement is indicated by rows. In data organization, rows represent horizontal collections of information that span across the width of a table or spreadsheet. Each row typically contains related data for a specific entity or record, enabling easy comparison and analysis across the various categories represented by columns.

In contrast, columns are vertical divisions in a table that typically represent different variables or fields of data for each record. Cells are the individual units where rows and columns intersect, holding specific pieces of data. Records refer to an entire set of data points pertaining to a single entry, usually corresponding to a row. Therefore, when considering the structure of data in a horizontal format, rows are the defining element.
