In an Excel document, which action should be taken if you want your information which falls across a selection of cells, to form part of one cell? Select all that apply:

Align text center button.  


Merge & center button.


Merge cells button. 


Merge across button.  

Merge & center button.

Merge cells button.

Merge across button.

The correct answers are:

- Merge & center button.
- Merge cells button.
- Merge across button.

To have your information across a selection of cells form part of one cell in an Excel document, the following actions should be taken:

1. Merge & center button: Select the cells that you want to merge, then click on the "Merge & Center" button in the toolbar. This will combine the selected cells into one cell and align the text in the center of the new merged cell.

2. Merge cells button: Select the cells that you want to merge, then click on the "Merge Cells" button in the toolbar. This will merge the selected cells into one cell without automatically centering the text.

3. Merge across button: Select the cells in a row that you want to merge, then click on the "Merge & Center" button and choose the "Merge Across" option from the dropdown menu. This will merge the selected cells horizontally and center the text in the merged cell.

So, to have your information across a selection of cells form part of one cell, you can select either the "Merge & Center" button or the "Merge across" button from the options given.
