Which statement best defines development?

Which statement best defines development?

• A. Increase in body size
• B. An increase in complexity, with progression along a continuous pathway
• C. A fixed, unchanging state
• D. Only physical milestones like walking

Answer: (B)

Development is the ongoing process of gaining more complex abilities and function over time, not just getting larger. It involves increasing complexity as skills build on earlier ones along a continuous pathway, across multiple areas like thinking, language, movement, and social interaction. That broader view explains why the best description goes beyond mere body size, and why it isn’t a fixed, unchanging state or limited to physical milestones like walking.
