Bob and George both live in the U. S. Bob recently asked for George's cell phone number, but George said he didn't have one. George would probably be considered a(n) in the diffusion of innovation process.

Laggard

Explanation:

The meaning of Laggard is that of a person who is very slow or who is far behind. This word can be adapted to what George has said about not having a cell phone these days. Today we live in the age of communication and information, where all people have a device that allows them to communicate with others, such as a telephone or computer. George, not having a phone, will make him look like someone who is not at the forefront of what today's society expresses, which is about constant and rapid communication.
