Question

You use Power Query Editor to preview a query that contains sales order data in the following columns:

  • Tax Amount
  • Sales Order ID
  • Freight Amount
  • Subtotal Amount
  • Total Item Quantity

The Sales Order ID column uniquely identifies each sales order. The Subtotal Amount and Total Item Quantity columns are always populated, but the Tax Amount and Freight Amount columns are sometimes null when an order has no associated amount. You need to query the data to identify the following metrics by month:

  • The average item quantity per order
  • The average freight amount per order
  • The maximum item quantity per order

How should you modify the query?

Options

  • AIn the Total Item Quantity column, replace the null values with 0.
  • BIn the Tax Amount column, remove rows that contain null values.
  • CIn the Freight Amount column, remove rows that contain null values.
  • DIn the Freight Amount column, replace the null values with 0.
