Alcohol's sedating effect tends to be reduced in teenagers compared with adults, so the noticeable signs of impairment develop more slowly. Because the brain and body of a teen respond less to that depressant effect, they don’t sense being impaired as quickly, even as alcohol affects them. This slower recognition explains why the statement is that teens take longer to sense impairment when compared to adults. The other ideas would imply they notice impairment sooner, are less susceptible overall, or that impairment is the same as adults, which doesn’t align with the reduced sedative response described.
