Casual behaviors that are generally and widely conformed to.

• A. Formal Norms
• B. Informal Norms
• C. Sanctions
• D. Language

Answer: (B)

Casual behaviors that most people follow reflect informal norms. These are unwritten expectations that guide everyday interactions—things you do automatically in social settings, like how close you stand when talking, how you greet someone, or waiting your turn in line. Because they aren’t codified in laws or official rules, they rely on shared understandings and social pressure rather than formal enforcement. When someone slips, informal sanctions—disapproval, gossip, awkwardness, or social exclusion—usually observed rather than legal penalties—kick in. In contrast, formal norms are codified and enforced by institutions, sanctions can be formal or informal but aren’t the behavior itself, and language is a means of communication, not the behavior under consideration. So the described scenario best fits informal norms.
