Answer: A
The essence of the scalar principle is unity of command.
The scalar principle, Mooney and Reiley's scalar process and Fayol's scalar chain, arranges an organisation in a graded chain of authority from the top to the bottom. Each member stands in one line and receives orders from the one superior directly above him, which is what unity of command means. A chain in which a person had several masters would no longer be a single scalar line.
Span of control is a separate principle about how many subordinates one superior can supervise. Communication travels along the chain, and co-ordination is the purpose the hierarchy serves, but neither is the defining feature of the chain itself.
