Final answer:
The keyboard shortcut to move to cell A1 in spreadsheet programs is Ctrl + Home. This shortcut instantly takes you to the beginning of the spreadsheet. The other options listed do not provide this function. So the correct answer is option C.
Step-by-step explanation:
The keyboard shortcut to move to cell A1 in spreadsheet programs like Microsoft Excel and Sheets is Ctrl + Home. This shortcut will instantly take you to the beginning of the spreadsheet, no matter where your current active cell is located.
The other options listed do not perform this specific function. Home typically moves the cursor to the beginning of the current row, Shift + Home extends the selection to the beginning of the current row, and there is no standard function for Alt + Home in spreadsheet applications.
Keyboard shortcuts for different operations are frequently unique to certain apps and operating systems. When utilizing a computer, keyboard shortcuts can greatly increase efficiency and productivity.
