Step-by-step explanation:
The correct statement is:
d. If Stan pays Mary a share of the commission, both Stan and Mary will be in violation of the license law.
According to the question, Mary, an Ohio broker, accompanied a customer to Florida and met with broker Stan. Mary violated the real estate license law by accompanying the customer to Florida without obtaining the proper license in Florida. Therefore, if Stan pays Mary a share of the commission, it would be considered aiding and abetting an unlicensed person, which is a violation of the license law for both Stan and Mary.
