Choice "C" is correct. Piecemeal opinions (opinions on parts of the financial statements, when those parts constitute a major portion of the financial statements) are not appropriate if the auditor has disclaimed an opinion or issued an adverse opinion, because they may overshadow the auditor's opinion on the financial statements taken as a whole. An opinion on specified elements that does not constitute a piecemeal opinion may be expressed, but should not accompany the disclaimer of opinion or the adverse opinion.
Choice "d" is incorrect. The auditor may express an opinion on one financial statement, even if the auditor must issue a disclaimer on the financial statements taken as a whole.
Choice "a" is incorrect. Even with adequate description in the scope paragraph, an opinion on the current asset portion of the balance sheet cannot be included in a disclaimer of opinion, as it might overshadow the disclaimer.
Choice "b" is incorrect. It is not appropriate to include an opinion on the current asset portion of the balance sheet in a disclaimer of opinion, as it might overshadow the disclaimer.
