A scope limitation sufficient to preclude an unqualified opinion always will result when management:__________
A) Prevents the auditor from reviewing the working papers of the predecessor auditor.
B) Engages the auditor after the year-end physical inventory is completed.
C) Requests that certain material accounts receivable not be confirmed.
D) Refuses to provide a representation letter acknowledging its responsibility for the fair presentation of the financial statements in conformity with GAAP.

A scope limitation in audit means circumstances hindering an auditor from carrying out his duties according to the audit procedure. A scope limitation can make an auditor issue a qualified opinion or a disclaimer of opinion depending on the materiality of the issue.

Back to the question, a scope limitation sufficient to preclude an unqualified opinion always will result when management refuses to provide a representation letter acknowledging its responsibility for the fair presentation of the financial statements in conformity with General Accepted Accounting Principle (GAAP)
