The answer is the third one: change the format of cells.

Explanation for each option:

1. Apply a graphic: This option is incorrect. Applying a graphic is typically done through the "Insert" tab or a similar section in most software applications, not through a dropdown in the Numbers group.

2. Sort all the information in a table: This option is incorrect. Sorting information in a table is usually done through a "Sort" feature, which is often found in the "Data" tab or a similar section, not specifically within the Numbers group.

3. Change the format of cells: This option is correct. The Numbers group in spreadsheet applications like Microsoft Excel or Google Sheets often includes options to change the format of cells, such as setting them to display as currency, percentages, dates, etc.

In summary, using a dropdown within the Numbers group of the ribbon allows you to change the format of cells.
