Final answer:
In assessing a conflict of interest for a firm assisting a tax client with the acquisition of an audit client, factors such as independence, audit objectivity, and confidentiality are key, but the size of the audit client is not relevant.
Step-by-step explanation:
When evaluating a potential conflict of interest in a scenario where a firm wishes to assist a tax client with plans to acquire an audit client, several factors should be considered. These factors include the firm's independence, the objectivity of the audit, and confidentiality concerns. However, one factor that is not relevant to the evaluation of a conflict of interest is the size of the audit client. The size may affect the audit work itself but does not inherently lead to a conflict of interest in the situation described.
