B. I would probably say b. It can't be a because we are not given all the information about all the teenagers. It says "NO teen" we are not given the minimum and maximum

It can't be c because the margin of error is plus/minus 112.

It's not d because we are not calculating anything for age so there can be no margin of error for age.
