There is no valid Apex statement out of all the choices that are available. You can try to input the different formulas and you will get the error message each time. The Apex statement is important because this will show the condition that each table will have in order to display the right data. Without the right formulas, people will be unable to get the information that they need.
Apex can do a lot of things for you. It will be easier to generate the professional and important data that you need as long as you would input the right information. Through the data that you will get, you can get significant cost savings too.
