Which of the following commands would you use to hide rows in a worksheet?

To hide rows in a worksheet, the most straightforward command to use is related to the concept of directly concealing the rows from view. The correct choice embodies this action by allowing users to select rows and hide them instantly from the worksheet.

When you utilize the command designated for hiding rows, it simplifies the process, making it an efficient way to manage visible data without deleting it. This command is instrumental when users want to declutter a worksheet or focus on specific data sets without losing the underlying information.

In contrast, other options cater to different functionalities. Formatting cells pertains to the appearance of cells—such as adjusting font, color, or borders—rather than concealing them. The grouping command is useful for organizing rows or columns, allowing them to be collapsed or expanded but not specifically for hiding. The filter command, while it does manage visibility by allowing users to display specific data, does so through criteria-based display rather than an on/off toggle for rows.

Thus, the command that directly addresses the action of concealing rows is the one that stands out as the correct choice.
