Answer:
This statement best reflects the concept of:
Radius of Significant Relationships.
Explanation:
The concept of radius of significant relationships is related to the groups of people who influence, guide, and shape an individual. Such groups change over the course of life, expanding, for example, during adulthood, but "shrinking" toward the end of that individual's life. The importance of those groups lies in the demands that result from their relationship with the individual. Those demands are age related, since they change according to what is expected from the individual at that moment in life.
