Answer:
A. Cultural lag.
Step-by-step explanation:
These are natural changes that occurs in a materials culture which could be drastic or slow.
The cultural lag concept was first theorized and the term was coined by William F. Ogburn, an American sociologist, in his book "Social Change With Respect to Culture and Original Nature," published in 1922. Ogden felt that materiality and by extension, the technology that promotes it advances at a rapid pace, whereas societal norms tend to resist change and advance much more slowly. Innovation surpasses adaptation and this creates conflict.
