Explanation: Data in a spreadsheet are organized in (3) rows and columns. In a spreadsheet, such as Microsoft Excel, data is arranged in a grid-like structure consisting of rows and columns. Each row is identified by a number, while each column is identified by a letter. The intersection of a row and a column is called a cell, which is the smallest unit of data in a spreadsheet. This row and column organization allows you to store and manipulate data in a structured and tabular format. Each cell can contain text, numbers, formulas, or other data types. By organizing data in rows and columns, you can easily input, manipulate, analyze, and visualize the data using various features and functions provided by the spreadsheet software. So, the correct answer is (3) rows and columns.
