Given the two data tables DT1 and DT2, to achieve the desired result where DT2 contains both the department and the names, the Merge Data Table activity should be configured to merge DT1 into DT2. This configuration requires specifying DT1 as the source table and DT2 as the destination table. The MissingSchemaAction should be set to AddWithKey which ensures that if the source table (DT1) contains columns that are not found in the destination table (DT2), they will be added to the destination table with the primary key information preserved.

Option A shows the correct configuration for the Merge Data Table activity to achieve this result:

Destination: DT1

Source: DT2

MissingSchemaAction: AddWithKey

This setup correctly adds the "Name" column from DT1 to DT2 based on the shared "ID" column, which acts as the key. Since both tables have an "ID" column with matching values, the names will be added to the corresponding IDs in DT2, resulting in a merged table with ID, Department, and Name columns.
