How long does puberty generally last?

• A. 8 years
• B. 4 years
• C. 7 years
• D. 5 years

Answer: (B)

Puberty is a multi-year period of hormonal-driven physical and sexual maturation. For most individuals, the process from its onset to its completion lasts about four years, though there is natural variation and it can range roughly from 2 to 5 years. That makes four years the best fit among the options for the typical duration.

Eight or seven years would generally exceed the common timeframe for puberty, while five years is longer than average. So, four years aligns most closely with what’s commonly observed.
