Final answer:
In a grocery store, when patrons give strange looks or whisper about someone wearing pajamas, they are displaying informal sanctions. These are society's ways of showing disapproval for behavior that doesn't align with societal norms, without any official actions.D is the correct answer.
Step-by-step explanation:
When you wear pajamas to a grocery store and notice people giving you strange looks and whispering to others, this is a demonstration of what is called informal sanctions. Informal sanctions are ways in which society expresses disapproval for deviant behavior outside of official rules or laws.
These are often expressed through gestures, comments, or looks rather than formal punishments or rewards. In this scenario, the other patrons are not officially punishing or formally acknowledging the deviance; instead, they are using facial expressions and whispers to show their disapproval of your attire, reflecting a social expectation of what is appropriate to wear in public.
This kind of behavior by other patrons serves to reinforce societal norms without any official measures.
