Step 1: Understanding the active cell.
In MS Excel (and other spreadsheets), the active cell is the one where the cursor is currently placed, and any data entered will go into that cell.
Step 2: How Excel shows the active cell's address.
- Row heading only displays row numbers, not the address.
- Status bar shows information like average, sum, or ready/edit mode, not the address.
- Name Box (located on the left side of the formula bar) always displays the address of the currently active cell.
- Formula bar shows the contents (data/formula) of the active cell, not its address.
Step 3: Conclusion.
Hence, the address of the active cell is displayed in the Name Box.
Final Answer: \[ \boxed{\text{Name Box}} \]
