Ateen gave up smoking to improve her lifestyle. what is another way to state what she did?

a. she changed her environment.
b. she made a personal choice.
c. she continued a habit.
d. she established a priority.

Smoking is not a constant of the environment nor exactly a priority, however it is a habit and personal choice. Because changing a habit is not an answer option you are left with her making a personal choice, which is correct.

So "B" is the correct answer. 

The answer is true atleast i think

The answer would be a true statement
