Final answer:

Step-by-step explanation:
The term grandson or granddaughter refers to the grandparent relationship. This indicates a link in the family where the grandchild is the offspring of the person's son or daughter. The kinship terminology used for these relationships includes terms of reference and terms of address, where 'grandson' or 'granddaughter' would be terms of reference denoting the relationship to the grandparent, and terms like 'Grandpa' or 'Grandma' would be terms of address when speaking directly to these relatives. It's an example of a decent relationship, as grandchildren are considered to be in a direct line of descent from their grandparents.
Kinship charts represent these relationships, and anthropologists classify them to understand family structures and relationships within different cultures. In a typical extended family, it might be common to find multiple generations living together or actively involved in each other's lives, potentially including grandparents with a primary caregiving role. The correct option is c. Grandparent relationship
