Puberty is distinct from other adolescent changes primarily by which characteristic?

• A. It's psychological.
• B. It's social.
• C. It's emotional.
• D. It's physical.

Answer: (D)

Puberty is defined by physical, biological maturation driven by hormones. It brings tangible changes in the body—growth spurts, development of primary and secondary sexual characteristics, and the onset of reproductive capability. These are observable, measurable body changes that distinguish puberty from other adolescent shifts. Emotional, social, and psychological changes may accompany adolescence, but the key feature of puberty itself is the physical maturation of the body.
