The correct answer is: A. Label
A label is a text string that identifies a cell or range of cells. It can be used to describe the data in the cell or range, or to make the spreadsheet easier to read.
A value is a number, date, or time that is stored in a cell. It can be used in calculations, or to represent data.
A formula is a set of instructions that tells Excel to perform a calculation. It can be used to add, subtract, multiply, divide, or perform other operations on values in cells.
A text string is a sequence of characters that is not a number, date, or time. It can be used to represent text, such as a name, address, or description.
In the case of the cell entry January 1, 2020, Excel would probably consider it to be a label because it is a text string that identifies the data in the cell.
