Final answer:
Erik should not pass on the information about the seller's motivation unless the buyer specifically asks for it in this situation.
Step-by-step explanation:
The correct answer is d) No, he shouldn't tell unless the buyer specifically asks.
As a real estate agent, Erik has a duty to act in the best interests of his client. By disclosing the seller's motivation to accept a lower offer, Erik would be compromising his buyer-client's negotiating position. As such, he should not pass on this information unless the buyer specifically asks for it.
