• Chose CD1

  C&D are the right ones

  CD is the correct one. A is wrong, we can't set the datatype as decimal number because it is a string B is wrong because we do need the customer key to count the customers for each order. C OK, because we don't need the columns for the analysis D OK, we can filter to the specified region as requirements

  C and D are correct. C. Since these columns are not needed for the specified analysis, removing them can reduce the data size and improve performance. D. By filtering the data to include only the NothWest region, we reduce the volume of data that needs to be processed, further improving performance.
