The placement of information within a cell at the left edge, right edge, or centered is :

Here's why alignment is the most fitting term:

Indentation: Indentation is typically used in word processing to control the text's position relative to the margin. While some spreadsheet software might offer limited indentation options for text within cells, it's not the primary use case for alignment.

Placement: Placement is a broader term that could encompass alignment but doesn't specify the horizontal positioning within a cell.

Identification: Identification refers to assigning a unique identifier to a cell (usually its address), not its content positioning.

Alignment: This term precisely describes the way information (text, numbers, etc.) is positioned within a cell relative to its edges (left, right, center). Spreadsheets offer various alignment options like left-aligned, right-aligned, or centered alignment, allowing you to format the data for better readability and presentation.

Therefore, alignment is the most specific and accurate term for describing the placement of information within a spreadsheet cell.
