The question "Is the question an element from the choices below" is a bit unclear, but if you are asking whether "No president or head leader" is one of the elements in the choices provided, the answer would be:
B. Articles of Confederation
The Articles of Confederation, which served as the first constitution for the United States, did not establish a strong central government and did not provide for a president or head leader. In contrast, a constitution generally refers to a system of fundamental principles, which can include the structure of government that often encompasses a presidency.
