What is the impact of adolescent weight gain relative to height development?

The correct answer reflects the understanding that both genders experience similar growth patterns during adolescence. During this developmental stage, growth is generally characterized by simultaneous increases in both weight and height. This means that as adolescents grow taller, they typically also gain weight in a proportionate manner that is influenced by factors such as genetics, nutrition, and overall health.

While it is true that there may be variations in the timing and rate of growth between boys and girls—often influenced by puberty—both genders generally follow a similar trajectory of growth. This simultaneous gain supports the overall balance necessary for healthy development, where a substantial increase in weight is accompanied by height increase, ensuring that the proportions remain appropriate for their growing bodies.

On the other hand, the other options suggest scenarios that deviate from this balanced growth, such as weight gain occurring without corresponding height increase or suggesting that only one gender experiences such growth patterns. These scenarios do not accurately reflect the typical biological processes involved in adolescent growth and development.
