Concept:Child development is shaped by both inherited traits and the surrounding environment working together.
Explanation:Heredity gives the basic potential – inborn traits, instincts, and IQ limits.
Environment decides how that potential is used – all mental and social skills depend on it.
For example, heredity sets a range for IQ, but environment determines where within that range a child’s IQ falls.
Both factors are complementary: heredity provides the raw material, and environment molds the final outcome.
Thus, a child’s growth and development are not due to heredity or environment alone, but through their continuous interaction.
Answer:D. interaction between heredity and environment
