How are cells identified in a spreadsheet?

• A. By its color.
• B. By the sum of values in the cell.
• C. By combining the column letter and row number.
• D. By the numeric value stored.

Answer: (C)

In a spreadsheet, a cell is identified by its coordinates on the grid, formed from the column letter and the row number. The column is labeled with letters (A, B, C, …, AA, AB, etc.) and the row with numbers (1, 2, 3, …). The combination of a column and a row uniquely locates a single cell, such as A1 in the top-left corner or C5 further down the sheet. This identification is what formulas use to reference data, like =SUM(A1:A10) or =B2+C3.

Color, the sum of values, or the numeric value stored in a cell do not define its location. Color is formatting, value is the content, and different cells can share the same value, so none of those alone identifies the cell's position.
