An independent audit adds value to the communication of financial information because the audit:

a. Confirms the exact accuracy of management's financial representations.

b. Lends credibility to the financial statements.

c. Guarantees that financial data are fairly presented.

d. Assures the readers of financial statements that any fraudulent activity has been corrected.

I know the answer is 'b. Lends credibility to the financial statements.' But please explain why all the other answers are not the correct answers. Thank you!
