Four small real estate firms formed a cooperative advertising group to share the high cost of larger display advertisements that would draw more attention to their listings. Calling their group "Sell4U," they began running a weekly half column. In addition to the names and numbers of all four firms, these advertisements must clearly state
A. which firm has listed each of the properties advertised.
B. that Sell4U is a cooperative group and not a national real estate franchise.
C. whether all of the Sell4U real estate firms use the same commission structure.
D. That complaints must be directed to individual firms and not the Sell4U group.
