Solution

The correct option is B
The more the steep the slope of the distance-time graph, the higher the speed is. Himanshu drove the car at $40 kmph$ , and then increased the speed to $50 kmph$ . So, the slope would be constant until $40 kmph$ , and then it deviates to $50 kmph$ . Using this information, we can say that the graph would like this:
