Puberty in girls typically begins around which ages?

• A. 7-8
• B. 9-10
• C. 11-12
• D. 13-14

Answer: (B)

Puberty in girls typically begins around 9 to 10 years of age, with the first visible change usually being breast development (thelarche). This marks the start of the pubertal process driven by rising estrogen and other hormonal changes, followed by a growth spurt, development of pubic hair, and eventually menarche around 12 to 13 years old. While there is natural variation, this 9–10 age range is considered the usual onset for most girls. Starting as early as 7–8 would be earlier than average and may indicate precocious puberty, while starting at 11–12 is within the broader normal window but later than the typical onset. Thus, 9–10 best describes when puberty commonly begins.
