Teylor Swift is a developer at your company and is setting up a data flow transformation to merge 2 data sources. 1 source contains item data and the other source contains data regarding the company which made the item.

The 2 data sources use SQL Server and have a 3-character CompanyCode column. Both data sources contain an ORDER BY clause to sort the data by CompanyCode in ascending order. 

Teylor wants to make sure that the Merge Join transformation works without additional transformations. What would you recommend?
A: Change the ORDER BY clause on the item source to order by ItemName.
B: Set the appropriate SortKeyPosition properties on the data sources.
C: Set the IsSorted property on both data sources.
D: Change the Merge Join transformation to a Merge transformation.
