As teens move through adolescence,
a. freedom increases, but so does responsibility
b. freedom decreases and responsibility increases
c. freedom increases and expectations decrease
d. freedom decreases, but expectations increase

As teens move through adolescence, 

A.  Freedom increases, but so does responsibility.

This is because it is the only answer that makes sense.  When you become a teenager, your parents give you more freedom, but it is up to you to make sure that you control this new freedom in a responsible way.

The answer isn't B or D, because freedom increases as you grow older; it doesn't decrease as these answer choices suggest.

The answer isn't C, because as teens move through adolescence, their parent's expectations increase as they give them more freedom.

So, the answer is A.

The answer is organisational websites.
