Approximately how many years does puberty last?

• A. 4 years
• B. 2 years
• C. 6 years
• D. 8 years

Answer: (A)

Puberty is the period when the body undergoes physical and sexual maturation driven by hormones, and it typically unfolds over several years rather than in a single moment. For most people, the entire process—from the first noticeable changes (like initial breast development or testicular enlargement) to the point where maturation is largely complete—lasts about four years. There is variation: girls often begin earlier and complete sooner than boys, and the growth spurt itself lasts roughly two to three years within that window. Among the given options, four years aligns closest with the average duration, whereas shorter (two years) or longer spans (six or eight years) are less representative of the typical course.
