Concept:In MS Excel, a cell address is the unique reference of a cell, formed by combining a column letter with a row number.Explanation:Each worksheet is divided into columns and rows.Columns are labelled alphabetically as $A, B, C, D, \ldots$ and rows are numbered as $1, 2, 3, \ldots$A cell address always starts with the column letter, followed by the row number.For example, $A1$ refers to the cell at the intersection of column $A$ and row $1$.Similarly, $B5$ refers to the cell in column $B$ and row $5$, and $F10$ refers to the cell in column $F$ and row $10$.This combination gives a precise location for entering data, building formulas, and navigating the sheet.For instance, the formula $=A1+B5$ uses the cell addresses $A1$ and $B5$ to add their values.The other options are incorrect because rows are not labelled with letters, and columns are not labelled with numbers in Excel.Therefore, a valid cell address must use a column letter with a row number.Answer:Option A: Column letter plus row number.
