Concept:Each domain of development is primarily influenced by either maturation (internal biological timetable) or environment (external experiences).
Explanation:Social development refers to learning to interact, form relationships, and understand social norms. This learning comes directly from the environment—family, peers, and society.
Physical development (body growth and changes) is largely driven by maturation, not environment.
Cognitive development (thinking and reasoning) follows a fixed sequence of stages based on maturation, as Piaget explained.
Emotional development also has a maturational basis for basic emotions, but expression is shaped by environment.
Therefore, the only correct match is Social Development with Environment.
Answer:Option C: Social Development - Environment.
