Answer : 2. "range"
Explanation :

Actually, the modification of the work done in a cell in Excel is typically referred to as "editing" the cell, not "range." Editing a cell means changing or modifying the data or formula within that specific cell. A "range" in Excel refers to a group of two or more cells on a worksheet.
