A supply manager is evaluating responses to a request for information (RFI) seeking off-site communications training for company employees. The supply manager receives a request from the vice president of marketing for a list of all respondents to the RFI, explaining that a letter will be sent to the respondents outlining the company's services and the importance of security at training facilities, and strongly implying that organizations who do business with the company will have an advantage in future proposal evaluations.

Q. Which of the following is the BEST response the supply manager can make in this situation?

a)Explain to the vice president that such a letter might be construed as attempted coercion or restraint of trade

b)Refrain from endorsing or prohibiting the letter, as it is not being sent from supply management

c)Remind the vice president that marketing is not part of the proposal evaluation process

d)Document the procurement files to ensure that suppliers' purchases are not included as evaluation factors
