Answer: Option A
Explanation: An auditor refers to an individual who is certified by an authority to perform an audit. The auditor provides an independent opinion as if the statements of the company are prepared as per the accounting and auditing standards.
Fraud examiners are the individuals who investigates an activity which is concluded to be a fraud already.
The difference between the two is, the auditor initially ascertains if there is a fraud while the fraud examiner tries to ascertain who is guilty of performing the fraud.
Hence from the above we can conclude that the correct option is A.
