Answer:
A. Social referencing
Step-by-step explanation:
Social referral is a term that refers to the mechanism that allows babies to display recognition and affection for someone or an object. An example of this is when babies who are in the presence of strangers, or people they do not often see, show themselves to be closer to their parents as a sign of recognition, security, and affection, as Aaron did. Aron doesn't see his uncle frank often, so he always runs close to his mother when his uncle approaches.
