A member uses data from a vendor without verifying its reliability and then defends the use to clients.

• A. Standard V.A Diligence and Reasonable Basis
• B. Standard I.C Misrepresentation
• C. Standard VI.B Priority of Transactions
• D. Code of Ethics and Standards

Answer: (A)

The central rule here is that professionals must base investment conclusions on a diligent, verifiable, and reasonable basis. Using data from a vendor without checking its reliability means the analysis rests on potentially untrustworthy information. When the member defends that data to clients, they’re presenting an unverified claim as if it were solid, which violates the obligation to perform adequate due diligence and to ensure that recommendations are supported by reliable information. If verification isn’t possible, the analyst should seek alternative sources or clearly disclose the data’s limitations and the verification performed. This fits best with the standard on Diligence and Reasonable Basis. The other options don’t map as directly: misrepresentation would involve knowingly false statements about the data, which isn’t explicitly stated here; priority of transactions concerns execution order and conflicts in trading, not data reliability; the Code of Ethics and Standards is too broad to pinpoint the specific expectation violated.
