Alex, a fraud examiner, receives an anonymous call from someone who claims to have information regarding a fraud at Alex's company. The whistleblower says he will only provide the information if he is given unqualified confidentiality. Alex says he cannot make that promise. Was Alex's statement prudent under the circumstances?
A. No, because whistleblowers are allowed unqualified confidentiality.
B. Yes, because Alex may attempt to protect the whistleblower's confidentiality, but cannot guarantee it.
C. No, because Alex will likely lose the whistleblower as a source, resulting in harm to his client.
D. Yes, because Alex must report all details concerning the whistleblower to his client.
