Answers
D.
Review of developer comments in executable code
Suggested answer: C

Explanation:

Source code synchronization is the process of ensuring that the source code and the object code (the compiled version of the source code) are consistent and up-to-date1. When program changes are implemented, the source code should be recompiled to generate a new object code that reflects the changes. However, if the source code is not recompiled, there is a risk that the object code may be outdated or incorrect.A compensating control is a measure that reduces the risk of an existing control weakness or deficiency2. A compensating control for source code synchronization is to compare the date stamping of the source and object code.Date stamping is a method of recording the date and time when a file is created or modified3. By comparing the date stamping of the source and object code, one can verify if they are synchronized or not. If the date stamping of the source code is newer than the object code, it means that the source code has been changed but not recompiled. If the date stamping of the object code is newer than the source code, it means that the object code has been compiled from a different source code. If the date stamping of both files are identical, it means that they are synchronized.
