Question

Quizplus · Accepted Answer

The beginning of adolescence is marked by the onset of puberty, which is characterized by hormonal and physical changes, including the development of secondary sex characteristics such as breasts and facial hair.

Note: A, B, and D are incorrect because full adult height is typically reached later in adolescence, assumption of adult roles may occur at different times depending on cultural and societal norms, and secretion of growth hormone is a normal part of human growth and development but is not a specific marker of the beginning of adolescence.
