Show answer & explanation
Correct answer: B
Answer: .xlsx
.xlsx is the file extension used for Excel workbook files created by Excel 2007 and later. It uses the Office Open XML format.
Modern Excel workbooks: .xlsx (Excel 2007+)
Older Excel workbooks: .xls (used before Excel 2007)
The other choices ('xcl', 'xelx', and 'excel') are not valid Excel file extensions; 'excel' is the program name, not a file extension.
