The correct answer is that treaty falls under higher levels of statutory authority, while regulation, statute, and ordinance are considered lower levels. Treaties are formal agreements between sovereign states or international organizations and often hold significant legal weight; they are subject to ratification and generally have priority over other forms of domestic law in cases of conflict.

On the other hand, regulations are created by governmental agencies based on existing statutes, statutes are laws enacted by legislatures, and ordinances are laws set by local government bodies. These lower levels of authority derive their power from higher laws and typically operate within the scope defined by those laws. Thus, treaties are distinctly categorized apart from these lower levels, affirming that treaty is not included in the list of lower levels of statutory authority.
