Concept:Social development depends on the combined influence of inherited traits and surrounding conditions.
Explanation:Heredity includes the genetic qualities passed from parents to offspring, such as temperament and intellectual ability.
These traits create the basic blueprint for a child's social behaviour.
Environment includes family, school, friends, and community, which shape how these traits are expressed.
Environmental factors provide opportunities, encouragement, and challenges that help a child grow socially.
Neither heredity nor environment works alone.
Their interaction is continuous and dynamic, meaning changes in one area can affect the other.
For example, a child may inherit a cautious temperament, but a supportive environment can help them become confident and sociable.
Thus, heredity gives the potential, while environment helps realise that potential.
Both are equally important factors in social development.
Answer:Option D: Heredity & Environment.
