Concept:Development is a continuous process that lasts from conception to death. Both motor and cognitive abilities grow and change across all life stages.Explanation:Motor development involves learning and refining physical skills like walking, writing, or dancing. Cognitive development covers thinking, reasoning, problem-solving, and memory. These two domains do not stop after childhood or adolescence. They evolve throughout adulthood and even old age. For example, adults learn new motor skills (e.g., playing an instrument) and improve cognitive functions (e.g., acquiring new knowledge). Development is lifelong, integrated, and includes quantitative and qualitative changes. It cannot be measured only at fixed periods; it continues from the womb to the tomb.Answer:D. Throughout the lifespan.
