Explanation
Explanation: A differential job consists of all the files that have changed since the last full backup. With differentials, you only have to restore the most recent differential backup since the last full backup, because the differential contains all the files that have changed since the full backup in their latest versions. Since the question mentions that the differential backup of the Wednesday night failed you only need to use the data backed up through the Tuesday night. Incorrect answers: A: This option will not obtain all the relevant uncorrupted data. C: This will include corrupted data. D: This option includes corrupted data.
