How would you describe someone who is antisocial?

The choice that describes someone who is antisocial is accurately identified as lacking sociable instincts or practices. An antisocial individual typically has difficulty forming or maintaining relationships and may struggle with understanding social norms. This can manifest as a preference for solitude, avoidance of social interactions, or a lack of desire to engage with others, all of which contribute to the characterization of antisocial behavior.

In contrast, the other choices depict traits of individuals who are social and engaged with their communities, which fundamentally contrasts with the concept of being antisocial. A person described as friendly and outgoing would embody sociable tendencies rather than lack them. Similarly, someone who is very active in community events demonstrates engagement and a desire to connect with others, while a well-adjusted member of society would exhibit the social skills and norms typical of healthy interpersonal relationships. Therefore, the correct answer captures the essence of what defines antisocial behavior.
