Final answer:
In the context of the IF function, to make a field remain blank, you should use the option c "" (an empty string). This will ensure that no text appears in the cell when the condition is true.
Step-by-step explanation:
In Microsoft Excel and other spreadsheet programs, when using the IF function, if the user wants a field to remain blank when a certain condition is met, the correct symbol to use is option c, which is "" (a pair of double quotes with nothing in between). These quotes represent an empty string in most programming languages and software applications, which means that no text will appear in the cell if the condition of the IF statement is true. For instance, if you want to display nothing when a certain cell's value is 0, you would write the IF function as =IF(A1=0, "", "Not Zero"). In this example, if cell A1 contains the value 0, the result displayed would be a blank cell.
