Answer:
The correct answer is d. The proper safeguarding of client information.
Step-by-step explanation:
According to chapter 3 of the GAO Yellow Book, the following are the ethical principles:
- The public Interest
- Integrity
- Objectivity
- The proper use of government information, resources, and position.
- Professional behavior.
Proper protection of customer information is not an ethical principle in this book, but it should be a factor to consider in the information manipulation process.
