Hierarchical diffusion is the spread of an idea from:

• A. Random individuals
• B. Persons of power to other persons
• C. Remote communities to urban areas
• D. From periphery to center

Answer: (B)

Hierarchical diffusion describes how an idea spreads first through more influential or connected parts of a network and then to others with less power or prominence. This pattern fits the notion of spreading from persons of power to other persons, since leaders, celebrities, or major urban centers often introduce innovations or trends that eventually reach wider, less influential audiences. For example, a new technology might be adopted first by major firms or cities and only later by smaller towns and individuals. The other scenarios don’t capture that influence-driven flow: random spread implies no guiding pattern, spread from remote communities to urban areas runs opposite to the usual center-to-periphery flow, and moving from periphery to center is also the reverse of the typical hierarchical path.
