Final answer:
CPA Kara Rambo's audit independence will not be considered impaired if she owns an insignificant amount of stock in Ajax Corporation.
Step-by-step explanation:
Auditor independence is a crucial principle in the field of accounting. As a Certified Public Accountant (CPA), Kara Rambo must maintain independence to ensure an unbiased audit of Ajax Corporation. Therefore, options b, c, and d would impair her audit independence.
Option a, owning stock in Ajax Corporation, may also create a conflict of interest. However, if Kara owns an insignificant amount of stock that does not influence her professional judgment, her independence may not be impaired.
