The glucose level in this graph is the dependent variable as its level in the blood relies upon the time and as time changes its level is likewise changing. So it has been set on Y-axis.

If any of the above people have diabetes, unquestionably it is individual B in light of the fact that as the diagram shows the glucose level in this present individual's blood glucose level is in every case more than 140, and level more than 140 for quite a while isn't viewed as typical. So this individual has diabetes.
