Answer:
The correct option is option A) The type of opinion the auditor should express under these circumstances under U.S. auditing standards is Un-modified with an emphasis-of-matter paragraph.
Step-by-step explanation:
Since the auditor is satisfied that sufficient audit evidence supports management's assertions about the nature and disclosure of the uncertainty, his/her opinion will be un-modified.
Unmodified opinion is the opinion where auditor expresses an opinion that financial statements are presented, in all material respects, in accordance with applicable financial reporting framework.
However, there is need for emphasis of matter paragraph to indicates that the auditor's opinion is not modified with respect to the matter emphasized because the ultimate outcome of the litigation cannot presently be determined.
