Answer: (A)

Development is about systematic changes and continuities in an individual that occur from conception to death. It isn’t a random sequence of events after birth; rather, it unfolds in a coordinated way across the entire lifespan, shaped by both biology and experience. This process covers physical growth, cognitive development, and social-emotional changes, as well as enduring traits that persist even as other aspects change. So you see someone growing, learning, adapting to new roles, and aging over time, while some stable aspects of personality or temperament remain. It’s not limited to physical growth alone, and it isn’t dictated by genetics alone with a fixed set of stages; development is a lifelong interplay of biological factors and environmental influences.
