Final answer:
The auditor's responsibility for reviewing subsequent events is limited to the period from the balance sheet date to the date the registration statement becomes effective.
Step-by-step explanation:
The auditor's responsibility for reviewing the subsequent events of a public company that is about to issue new securities is normally limited to the period of time beginning with the balance sheet date and ending with the date the registration statement becomes effective (option D). Subsequent events are events that occur after the balance sheet date but before the issuance of the financial statements. These events need to be evaluated by the auditor to determine if they have any significant impact on the financial statements being issued. By limiting the review to the period from the balance sheet date to the date the registration statement becomes effective, the auditor ensures that any material subsequent events that could affect the company's financial position are appropriately disclosed in the financial statements provided to potential investors.
