Correct option is C
In Microsoft Excel 2019, pressing the Escape (Esc) key while typing in a cell will cancel the entry. This discards any data typed into the cell and reverts it to its previous value or leaves it blank if it was empty.
Important Key Points:
Escape key cancels the current edit mode without making changes.
It works only before you press Enter or move to another cell.
Useful when you accidentally start typing and want to exit without saving the entry.
Knowledge Booster:
Tab moves the selection to the next cell in the row and accepts the entry.
Arrow keys also confirm the entry and move the selection accordingly.
Space bar enters a blank space into the cell but does not cancel input.
