[International Expansion] Ryan Wants to Expand His Coffee Business into Winland

[International Expansion] Ryan wants to expand his coffee business into Winland, a small, remote country. He moves to Winland temporarily in order to oversee operations. His friend Terrell asks him if he plans to hire legal counsel for the expansion. Ryan replies, "Of course not. The U.S. has the strictest laws regarding contracts, employment, and business practices in the world. So long as I'm legal in the U.S., I'm legal anywhere. Besides, I studied up on Winland law ten years ago, and I know it all." Ryan proceeds and lands in jail in Winland for violating recently passed laws which make it a crime to mistreat employees and which criminalized the failure to provide certain benefits. Authorities in Winland claim that he sexually harassed an employee, failed to pay sufficient wages, and failed to give employees Winland's mandated 12 weeks of paid vacation per year.
-What is true regarding Ryan's defense that he thought he knew the law of Winland because he had studied it some years before and that the laws under which he was arrested were new? (Assume the law of Winland is the same as the U.S. on this issue.)

A) Rules change and Ryan had a duty to stay current. It is not a defense that he studied the law at one time and that the laws at issue were new.
B) Ryan is entitled to rely as a defense on the fact that he had studied the law at one time. Officials in Winland were charged with publicizing any changes.
C) If Ryan can prove that the laws at issue were passed within the last twelve months before he was arrested, he will get out of jail because there is a twelve month grace period for new laws.
D) If Ryan can prove that the laws at issue were passed within the last six months before he was arrested, he will get out of jail because there is a six month grace period for new laws.
E) Ryan cannot be prosecuted so long as he was not aware he was violating the law. He did not have the requisite intent to perform a criminal act, regardless of whether the laws were new.
