Answer:
Option B = Anna Freud.
Step-by-step explanation:
The woman named Anna Freud was born on the 3rd day of the month of December in the year 1895 in Vienna, Austria. Before her demise on the 9th day of the month of August in the year 1982 in London, United Kingdom, she was a psychoanalyst and contributed to the study of Psychology in children.
When Anna was still alive, she formed and developed many theories ( such as ego Psychology) and so many techniques that can aid in knowing more about Psychology of young ones. To Anna, every child is unique.
Hence, Anna Freud would be the one to argue that the physical changes of puberty cause substantial disruption and conflict inside the family system.
