In violation of a state licensing statute, Jones purports to be an attorney. After making that allegation, he contracts to perform legal service for Smith. Smith then pays Jones a $$500$ retainer. Later, after discovering that Jones is not licensed and therefore cannot get the job done, Smith sues Jones for the $$500.$ What is the most likely result, and why?

A$)$ Smith definitely wins, because here we have a revenue$-$raising statute.

B$)$ Smith probably wins, because parties for whose protection a regulatory statute has been enacted often can recover amounts paid under a contract declared illegal by the statute.

C$)$ Smith definitely loses, because here we have a regulatory statute.

D$)$ Smith probably loses, because the law obligates one to check the licensure of a professional with whom one deals.
