In the given options, the principle that clearly refers to the arrangement of things and people is:
A. Order
Order involves organizing things and people in a structured and systematic way. It pertains to the way elements are arranged to promote efficiency, clarity, and organization. For example, arranging books on a shelf alphabetically or chronologically is an application of the principle of order.
While disciplines, scalar chair, and equity are important concepts, they do not specifically relate to the arrangement of things and people as directly as the principle of order does.
