A broker had listed lots for sale in a subdivision. In order to generate interest, the broker conducted a direct mailing of cards. The recipients of the card were told that if they filed in their names on the cards and mailed them back to the broker along with $100 registration fee, they may be selected through a drawing to win lot. Which is a correct statement?

a. There is nothing wrong with this plan, If Broker does what was promised.

b. A plan of this type has declared by the Florida Real Estate Commission to be a plan of selling, which endangers the public interest.

c. If no one returns the cards and a drawing for a free lot could not be held, Broker did not violate any rules promulgated by the Florida Real Estate Commission.

d. If Broker had advertised this plan in a newspaper of general circulation, rather than by the use of direct mail, the plan would be approved by the Florida Real Estate Commission.
