Final answer:
The auditor does not typically review each program change request in a responsibility system of computer program development and maintenance.
Step-by-step explanation:
The correct answer is b) A review of each program change request by an internal auditor.
When conducting a review of a responsibility system of computer program development and maintenance, an auditor typically checks for proper documentation of program changes, proper costing of change requests, and matches between program documentation and the production version of the program.
However, the internal auditor does not typically review each program change request as part of this process.
