During an experiment, the time of an object was measured every 20 meters. Each researcher measured the object's motion on different surfaces, noted as A, B, C, and D. Their average data of the trials are shown below.


Distance (cm) 0 20 40 60 80 100
Time A (s) 0 5.23 10.11 14.68 18.54 23.36
Time B (s) 0 4.66 9.33 13.97 18.63 23.31
Time C (s) 0 3.57 7.44 11.32 16.98 23.28
Time D (s) 0 5.00 15.00 40.00 60.00 85.00


Which of the surfaces allowed the object that was initially moving the fastest to slow down the most?
Surface A
Surface B
Surface C
Surface D
