The correct answer is D
Explanation
The second coordinate of a point on the graph corresponds to v. From the graph, you can see that for 0 less than or equal to t less than or equal to 5, the smallest value of v is 5 and the greatest value is 10, so 5 less than or equal to v less than or equal to 10.
