What does "scion" refer to?

The term "scion" is primarily used to refer to a descendant or heir, particularly in a familial or aristocratic context. It signifies someone who is part of a lineage or family, often implying that this person comes from a line of notable or wealthy ancestry. This understanding aligns with the broader usage of "scion" in literature and conversation, where it frequently denotes a person who inherits traits, responsibilities, or advantages associated with their family background.

While other options might seem plausible in different contexts, "scion" specifically captures the essence of succession and legacy, thus making "a descendant or heir" the most appropriate definition. The other choices refer to unrelated concepts, which do not pertain to the familial and hereditary implications that "scion" conveys.
