Answer: (storesDF.withColumnRenamed("division", "state") .withColumnRenamed("managerName", "managerFullName"))
The question requires renaming columns 'division' to 'state' and 'managerName' to 'managerFullName', which implies the original columns should be replaced. Option E uses `withColumnRenamed` correctly to rename both columns. Other options either use incorrect syntax (A, C), create new columns without removing the originals (B), or reverse the renaming logic (D).
