At puberty onset, which physical change is commonly observed in Tanner stage II?

Explanation:
The beginning of puberty is marked by Tanner stage II, when the first outward signs of pubertal development appear due to gonadal hormone changes. In girls, this is breast budding (thelarche); in boys, it is enlargement of the testes (often with scrotal changes). These early signs signal the shift from prepubertal to pubertal development. The growth spurt typically starts around this time and continues through later stages, not ends here. Menarche usually occurs after several more stages of breast development. Final adult height is reached only after growth plates close, much later than Tanner II.
