Final answer:
The option that allows you to perform a mathematical operation on the selected cells is the correct answer. Hence the correct answer is option 3
Step-by-step explanation:
The option that allows you to perform a mathematical operation on the selected cells is the correct answer. In Excel, the QUICKSUM function can be used to add the values of a range of selected cells. The formula for the QUICKSUM function is:
=QUICKSUM(range)
Where range is the range of cells you want to add. For example, if you want to add the values in cells A1 to A5, the formula would be =QUICKSUM(A1:A5).
Hence the correct answer is option 3
