Cell address $A$4 in a formula means it is a . * A. All of the above

B. Mixed cell reference

C. Relative cell reference

D. Absolute cell reference

The answer to this question is given below in the explanation section

Explanation:

Cell address $A$4 in a formula means it is an Absolute Cell Reference.

Absolute cell reference does not change when you copy the formula to other cells. when the $ symbol added in the front of the column and row, makes it absolute. It stops the row and column numbers from changing when you copy to other cells. The given $A$4 cell address contains the value in column A and row 4. It does not change the value when you copy the formula that has mentioned ($A$4) into other cells. For example, if you have value 10 at row 4 and column A. Then you multiple column B with A4 cell value and you want that A4 value will not change while copying formula from C1 to C10. You can use in column C1 as =B1*$A$4. Then you copy the formula to cell 10. The value of $A$4 will not change.

while the other options are not correct because:

In the relative cell reference values get changed in the formula, while in the mixed cell reference you can either locked the row or column while the row or column changes when the formula is copied respectively.
