Which of the following are the three domains of development?

The correct answer encompasses the three key domains of development, which are essential in the study of psychological growth and change across a lifespan. The physical domain refers to biological development, including changes in body size, physical health, and motor skills. The cognitive domain involves intellectual processes like thinking, reasoning, and problem-solving, capturing how individuals acquire, process, and store information. The psychosocial domain highlights the interplay between psychological aspects and social factors, emphasizing the development of identity, relationships, and social skills.

This framework is foundational in developmental psychology as it allows researchers and practitioners to understand how different aspects of a person's life interact with each other over time, influencing overall development. The other options either mix or mislabel these domains, which could lead to confusion about the distinct areas of focus in developmental studies.
