According to the text, the example of attitudes toward smoking in the U.S. demonstrates the notion that

A) perceptions of deviance are influenced by social change.
B) smoking should not have been considered acceptable.
C) laws, such as anti-smoking laws, are needed in order identify deviant behavior.
D) evidence of risk is enough to change behavior.

The example of attitudes toward smoking in the U.S. demonstrates how social change can influence perceptions of deviance. Smoking was once a widely accepted behavior, but through increased knowledge about the health risks and changing social norms, it has become increasingly stigmatized. Anti-smoking laws and policies have also played a role in shaping attitudes toward smoking as deviant behavior. The fact that perceptions of smoking have changed so dramatically over time highlights the influence of social factors on our definitions of deviance.
