Reference - International Expansion

Reference - International Expansion. Zach wants to expand his coffee business internationally-into Zeno, a small remote country in Africa. His best friend Zora asks him if he plans to hire legal counsel for the expansion. Zach replies, "Of course not. The U.S. has the most strict laws regarding contracts, employment, and business practices. So long as I'm legal here, I'm legal anywhere. Besides, I studied up on Zeno law ten years ago, and I know it all." Zach proceeds and lands in jail in the remote country of Zeno for violating recently past laws protecting employees and mandating certain benefits. Authorities there claim that he sexually harassed an employee, failed to pay sufficient wages, and failed to give employees Zeno's mandated 12 weeks of vacation per year. Which of the following is true regarding Zach's legal problems in Zeno?

A) Zach can rely upon the federal statutory laws of the U.S. as a defense but not his U.S. Constitutional rights.
B) Zach is entitled to all U.S. Constitutional rights in Zeno because he is a U.S. citizen, but he cannot rely on U.S. statutory rights.
C) Zach can rely upon the federal statutory laws of the U.S. as a defense, and he is also entitled to all U.S. Constitutional rights in Zeno because he is a U.S. citizen.
D) Zach must obey the laws of Zeno when operating a business in Zeno and cannot rely upon U.S. laws as a defense.
E) Zach is subject to civil laws but not criminal laws of Zeno.
