What is the short cut key to highlight the entire column? A. Ctrl + C B. Ctrl + Enter C. Ctrl + Page Up D. Ctrl + Space Bar

The correct answer is: D. Ctrl + Space Bar

To highlight the entire column in a spreadsheet, press and hold the Ctrl key, then press the Space Bar. This will highlight all of the cells in the column, from the top to the bottom.

The other options are incorrect. Ctrl + C copies the selected cells, Ctrl + Enter inserts a new row, and Ctrl + Page Up scrolls the window up one page.
