Answer: A) A1
Explanation: A cell reference or cell address is a combination of a column letter and a row number that identifies a cell on a worksheet. For example, A1 refers to the cell at the intersection of column A and row 1; B2 refers to the second cell in column B, and so on. Cell A1 on a worksheet marks the where the first row and the first column converge. Cell references in spreadsheet programmes like Microsoft Excel or Sheets are commonly expressed as column. Which worksheet cell address denotes the point where the first row and first column converge? A worksheet cell is identified by a combination of a column letter and a row number known as a cell reference or cell address. For instance, the cell at the junction of row 1 and column A is designated as A1.
