Final answer:
A C. Bell Curve graph is most appropriate for illustrating the Diffusion of Technology pattern, showing the initial adoption, rapid growth, and eventual decrease as a technology becomes saturated in the market.
Step-by-step explanation:
The kind of graph that can be used to describe the pattern of Diffusion of Technology is the Bell Curve. This is because when a new technology is introduced, the number of people adopting it usually increases, reaches a peak, and then eventually decreases as the technology reaches saturation within the market.
The Bell Curve effectively captures the lifecycle of a technology adoption, as conceptualized by sociologist Everett Rogers in his model of the diffusion of innovations.
This model captures the initial slow growth as innovators and early adopters begin to use the technology, followed by rapid growth as the early majority and late majority catch on, before slowing down again as the laggards make their adoption.
