Fiona is starting to utilize the protection capabilities of Excel 2019. For the Lock or Unlock Cells function to work, which option should be enabled?

In Excel, cells are marked as locked or unlocked in their formatting, but that setting only takes effect when the worksheet is protected. Fiona needs to enable Protect Worksheet for the lock or unlock settings to restrict editing. Protect Workbook controls the workbook’s structure, not cell editing.
