Which of the following code blocks returns a new DataFrame where column division from DataFrame storesDF has been renamed to state and column managerName from DataFrame storesDF has been renamed to managerFullName?





Explanation:

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).
