Microsoft Power BI Data Analyst Practice Question

You are working in the Power Query Editor with a table that contains product sales data. The table has a 'ProductName' column, followed by twelve columns representing each month's sales (e.g., 'Jan_Sales', 'Feb_Sales', 'Mar_Sales'). To create a time-series analysis, you need to restructure this data so that you have one column for the month and another for the sales amount, while retaining the product name for each row. Which single transformation should you apply to the twelve month columns to achieve this?
