Answer:
A. The child has secondary sex characteristics
Explanation:
The onset of puberty is marked by<em> "secondary sex characteristics."</em> This characteristics appear when the person is already sexually mature. <u>Examples of secondary characteristics are:</u>
<em>1. breast enlargement (in females)</em>
<em>2. pubic hair (both males and females)</em>
<em>3. Adam's apple (in males)</em>
<em>4. widening of hips (in females)</em>
<em>5. increased muscle mass (in males</em>)
The onset of puberty is not the same for everyone. However, it usually occurs from<em> 8 years old to 14 years old.</em> This makes choice B and choice D incorrect. Although the growth speeds up during puberty, the height of males and females vary. So we cannot assume that a child taller than 5 1/2 feet is at the onset of puberty. Some people are naturally born tall and may even be taller than 5 1/2 feet before puberty stage.
