Answer key

violates-care-reasonable-basis

Derivation from the cited text

The quoted prong requires the broker, in making the recommendation, to exercise reasonable diligence, care, and skill to understand the potential risks, rewards, and costs of the recommendation and to have a reasonable basis to believe it could be in the best interest of at least some retail customers. The stipulated facts state that neither the associated person nor the firm reviewed the note's structure, payoff formula, costs, or risks, and that the associated person cannot explain the return calculation. The understanding the prong requires is absent by stipulation, so the prong is violated. (Other obligations may also be implicated on these facts; this item asks only about the quoted prong.)

Rubric

Answers yes: the quoted reasonable-basis prong is violated on the stipulated facts.

Cited primary sources (quote-gated)
17 CFR § 240.15l-1 · (a)(2)(ii)(A)

Each quoted passage is exact-matched, after typographic normalization, against the corpus text fetched from the issuing authority (hashes in the corpus manifest). An item whose quote stops matching fails the build.

The key is correct. Initial logic and parameters are validated. The stipulated facts confirm the broker failed to understand the risks, rewards, and costs, directly violating the care obligation's reasonable-basis prong.

The stipulated facts state that neither the associated person nor the firm reviewed the note's structure, payoff formula, embedded costs, or risks, and that the associated person cannot explain how the note's return is calculated. Those facts directly negate the understanding required by the quoted reasonable-basis prong. Therefore the key's conclusion that the prong is violated is correct.
