Correct Answer - Option 2 : 1
By default, any new workbook you create in Excel will contain one worksheet, called Sheet1. To change the default number of worksheets, navigate to Backstage view, click Options, then choose the desired number of worksheets to include in each new workbook.
Hence the correct answer is 1.
Although you're limited to 255 sheets in a new workbook, Excel doesn't limit how many worksheets you can add after you've created a workbook. The only factor that ultimately limits the number of worksheets your workbook can hold is your computer's memory.
