Sol. The World Health Organization (WHO) defines adolescents as individuals between the ages of 10 to 19 years. This age group is considered a transitional phase from childhood to adulthood. It is a critical period for physical growth, mental development, and the onset of puberty. Many reproductive, nutritional, and mental health programs are targeted toward this specific group.
Explanation of each option:

· (d) 20–29 years – Incorrect. This age group falls under the youth or young adult category. They are included in other programs like skill development and employment, not adolescent health.
