This choice accurately describes the wide range of onset and progression of puberty for boys, with the age of onset ranging from 10-13 ½ years and the age of completion ranging from 13-17 years. Choice B and D also mention a range of ages, but they either include unrealistic early onset ages (8 years) or suggest an exact prediction of when puberty will begin, which is not accurate. Choice C is incorrect as there is some predictability within a broad range of years.
