The correct answer is option B

Dollar sign is often used in Excel to make a row or column absolute. It is used for absolute cell referencing, which tells Excel that you want to always refer to a particular cell even when yo copy the formula across other rows and columns.

The row or column that comes after the dollar sign is anchored or absolute.

All Excel formulas start with an “equal to” (=) sign. To calculate the tax on each sale, you need to multiply B2 and H2.

Hope this helps.
