The correct answer is D because the original sentence contains a dangling modifier - the introductory phrase "Having completed the audit" does not clearly identify who performed the action, making it ambiguous. By changing the sentence to include "the auditors" as the subject, the modifier now correctly refers to the noun that immediately follows it, creating a clear and logical connection between the action and the doer. The original sentence incorrectly implies that the financial statements completed the audit, which is illogical and violates the basic rule that a dangling modifier must have a clear antecedent. Other options likely fail because they either leave the dangling modifier unresolved, create new grammatical errors, or make unnecessary changes that don't address the core problem of missing or unclear agency in the sentence.
