An IS auditor performing an application maintenance audit would review the log of program changes for the:

A.
authorization of program changes.

B.
creation date of a current object module.

C.
number of program changes actually made.

D.
creation date of a current source program.

Explanation:
The manual log will most likely contain information on authorized changes to a program. Deliberate, unauthorized changes will not be documented by the responsible party. An automated log, found usually in library management products, and not a changelog would most likely contain date information for the source and executable modules.
