The first stage of any social change is

A) collective unrest.
B) disturbance.
C) innovation.
D) optimism.

The first stage of any social change is innovation, which refers to the introduction of new ideas, practices, or technologies that challenge the existing ways of doing things. This leads to a period of exploration and experimentation in which individuals and groups try to understand and adapt to the changes. Collective unrest and disturbance may occur later as people struggle to cope with the new realities brought about by the innovation, while optimism may arise once the benefits of the change become more apparent. But the initial stage is always innovation.
