Answer:
C. Proportional
Explanation:
As time passes, the number of labels printed will increase in number. Based on this, increase in time will result in increase in number of labels printed. Decrease in time will result in decrease in number of labels being printed hence:
Time ∝ Number of Labels Printed
(Time is directly proportional to number of labels printed)
Note : We cannot say double or decreasing as we do not have exact values to define that so those options are ruled out
