Final answer:
The correct option is C. When determining whether a proposed service would create a potential conflict of interest, it is important to consider whether a reasonable and informed third party would conclude that a conflict of interest exists.
Step-by-step explanation:
An important consideration when determining whether a proposed service would create a potential conflict of interest is whether a reasonable and informed third party would conclude that a conflict of interest exists.
For example, if your firm is proposing to assist Company X with plans to acquire your audit client, it is important to evaluate whether this creates a conflict of interest that may compromise the independence and objectivity of your firm's audit work.
Therefore, the correct answer is C. Whether a reasonable and informed third party would conclude that a conflict of interest exists.
