Answer:
Option (C)
Explanation:
From the graph attached,
Position of a car is changing with time.
Let the two points (1, 5) and (2, 10) define the positions of a car at the different moment of time.
Since, speed = [tex]\frac{\text{Distance traveled by the car}}{\text{Time taken}}[/tex]
           = [tex]\frac{10-5}{2-1}[/tex]
           = 5 meter per second
Speed of the car = slope of the line on the graph
Since slope of the line is constant, speed of the car will be constant.
Therefore, Option (C) will be the answer.
