What aspect of physical development increases significantly in children aged 15-18?

During the ages of 15 to 18, adolescents undergo significant physical, emotional, and social changes due to puberty and maturation. One of the most notable aspects during this age range is the heightened concern about body changes and appearance. This focus on self-image is driven by various factors, including social pressures, media influence, and the developmental task of establishing identity.

As adolescents transition into adulthood, they become more aware of their bodies and the way they are perceived by others. This often leads to increased self-consciousness and preoccupation with body image, which is a normal part of their developmental stage. Concerns may revolve around weight, height, skin conditions, and overall attractiveness, influencing their behavior and choices, including fashion and physical activity.

This period might also include a heightened desire for acceptance and validation from peers, which can exacerbate their focus on appearance. Thus, the correct answer reflects a critical aspect of adolescent development during this age range, where the interplay of physical changes and emerging social dynamics shapes their self-perception and concerns.
