The correct answer is Formula Bar. Formula Bar:Excel formula bar is a special toolbar at the top of the Excel worksheet window, labeled with function symbol (fx). We can use it to enter a new formula or copy an existing one. The formula bar comes very handily when we are dealing with a pretty long formula and we want to view it entirely without overlaying the contents of the neighbor cells. The formula bar gets activated as soon as we type an equal sign in any cell or click anywhere within the bar. Hence, the formula bar represents the contents of the active cell.
