Final answer:
During puberty, teens experience significant changes in their physical appearance which can impact their emotions and self-esteem. However, decreased energy levels and reduced appetite are not typically expected changes. So, the correct answer is option b.
Step-by-step explanation:
As a growing teen, you can expect lots of changes in physical appearance. Puberty brings about significant changes in height, weight, body shape, and the development of secondary sexual characteristics. These changes can lead to a range of emotions and a fluctuation in self-esteem. While emotions may not be stable at all times, it is important to note that decreased energy levels and a reduced appetite are not typically expected changes during adolescence.
So, the correct answer is option b.
