Alexxx [7]

Answer:

A) Feelings of invincibility

Explanation:

Adolescence refers to the period of human growth that occurs

between childhood and adulthood. Adolescence begins at around age

10 and ends around age 21. Adolescence can be broken into three

stages: early adolescence, middle adolescence, and late

adolescence. Each stage has its own characteristics. Let's take a

look at each stage in more detail below.

Middle adolescence is the second stage and occurs from ages 15 to

17. By this time, puberty has passed. Teens in this stage are

extremely concerned with how they look, and they think others are

concerned, too. They spend a large amount of time grooming,

exercising, and modifying their physical appearance.

Girls are especially preoccupied with their physical appearance and

being sexually attractive.

Relationships are often changing during middle adolescence. There

is also worry about sexual attractiveness. Middle adolescents

complain about their parents preventing them from becoming

independent, and they withdraw from them. They may try to assert

their independence by refusing to bathe, not cleaning their rooms,

and picking up annoying habits. There is an intense focus on peer

groups during middle adolescence, and teens in this stage tend to

confide in each other more than they do their parents.

As with early adolescence, teens in middle adolescence may feel

invincible. Risk-taking behaviors are significantly increased during

this stage. On the other hand, acting-out behaviors begin to

decrease, since teens in this stage have a better grasp on how to

use words as a means of expression.
