Step-by-step explanation:
The question seems to be related to a specific historical instance of an audit firm or auditor providing an unqualified opinion.
An unqualified opinion is an independent auditor's judgment that a company's financial records and statements are fairly and appropriately presented, and in accordance with Generally Accepted Accounting Principles (GAAP).

However, Arthur Andersen was a well-known audit firm that fell into disrepute after the Enron scandal, where it was found to have issued unqualified opinions on Enron's financial statements, which later turned out to be materially misstated.
So, the best annswer is 5, none of them.
