Final answer:
B) Isolate. In a sociogram, an unselected individual who is not connected or has few connections with others is referred to as an Isolate (B). This describes their status within the sociogram and does not carry a stigma of exclusion outside of this visual representation.
Step-by-step explanation:
In a sociogram, an unselected individual is referred to as an Isolate (B). A sociogram is a visual representation of the social dynamics within a group. It shows the relationships between members of a group by marking the interactions or the lack thereof. Those individuals who are unconnected or have few connections with others in the diagram are called isolates. This term is specific to their social interaction status within the sociogram and doesn't necessarily hold any stigma in the broader context outside of this specific representation.
An Isolate does not engage much, if at all, with others in the group, and therefore, is depicted without lines or arrows pointing to or from them. As opposed to outcast, nonconformist, or pariah—terms that can carry a sense of rejection or active exclusion—being an isolate simply means lacking connections or not being selected by others in a social network without the implication of negative judgment. The term 'Isolate' reflects social relationships within the network and does not necessarily indicate an individual's broader social standing.
