A dealer or salesperson must not imply that the commission amount is set by:

The correct choice indicates that a dealer or salesperson must not imply that the commission amount is dictated by a rule or regulation outside of negotiation. This underscores the principle that commissions should be the result of mutual agreement between the dealer and the client, rather than being influenced by external standards or mandated requirements that are not part of the negotiation process.

In many commercial sales contexts, the ability to negotiate terms, including commissions, is a fundamental aspect of the transaction. If a salesperson suggests that exclusive regulations or rules set the commission, it could undermine the negotiation process, leading clients to believe they have no room to negotiate or that certain fees are non-negotiable. This can result in misunderstandings or even legal issues if clients feel misled.

Moreover, it emphasizes the responsibility of salespeople to be transparent about how commissions work and to facilitate a fair negotiation environment. Commissions should reflect the agreed terms between the parties involved rather than the influence of external regulatory frameworks that do not allow for negotiation.
