Explanation:
Option B, the Data Flow activity, is the most suitable for handling schema differences in Azure Data Factory. The Data Flow activity allows you to create a custom mapping between the source and destination columns, regardless of the schema differences. By using the 'Derived Column' and 'Source' transformations, you can map the columns from the source dataset to the destination dataset, even if the column names or data types differ. This approach provides a flexible and efficient way to transform data with different schemas.
