Please help with the following Derivatives Question

The position (in thousands of feet) of a car driving along a straight road at time t in minutes is given by the function y = 5(t) that is pictured below. Let 1.:{t} denote the velocity of the car (in thousands of feet per minute] at time t (in minutes]. Which graph AF is the best representative of the derivative function v'{t)? ? v \f(Note: the vertical axes of these graphs may have been scaled to to t these functions. Click on a graph to enlarge it.) Which of the following statements are true? Select all that apply. I: A. If o'[t] is zero, then Mt} must be zero. I: B. The function o' represents the position ofthe car. C. There are times when v'[t) is zero and t} is not zero. D. When t} is positive, 11'[t} must also be positive. E. The function o' represents the acceleration of the car. F. When 11'[t} is negative, the car is slowing down. I: G. When o'(t} is negative, the car is moving backwards. I: H. None of the above statements are true
