Final answer:
Jane, as a CPA, breaches her duty of care to her client, Striker & Co., if she fails to adhere to auditing standards, remains biased, or does not diligently perform her audit.
Step-by-step explanation:
Jane is a CPA in charge of auditing her client, Striker & Co. Jane's duty of care to Striker will most likely be breached if Jane fails to exercise the level of skill and care that would be expected of a reasonably competent auditor under similar circumstances. This could include behaviors such as not adhering to Generally Accepted Auditing Standards (GAAS), not remaining objective or independent, or not performing due diligence in her examination of the company's financial statements.
