To study traffic flow along a major road, the city installs a device at the edge of the road at 1:00a.m.The device counts the cars driving past, and records the total periodically.The resulting data is plotted on a graph, with time (in hours since installation)on the horizontal axis and the number of cars on the vertical axis.The graph is shown below; it is the graph of the function C(t)= Total number of cars that have passed by after t hours.When is the traffic flow greatest?
A)2:00 am
B)3:00 am
C)4:00 am
D)5:00 am
