answer this please

From time t = 0s to time t = 10 s, an object moves in one dimension on a horizontal surface with a speed that increases as a function of time. Which of the following methods would give the most accurate estimate of the instantaneous acceleration of the object at t = 5 s? A Find the change in velocity between t = 10 s and t = 0s and divide that value by 10 s. B Find the change in velocity between t = 5.1s and t = 4.9 s and divide that value by 0.2 s. C Find the average velocity between t = 10 s and t = 0 s and divide that value by 10 s. D Find the average velocity between t = 5.1s and t = 4.9s and divide that value by 0.2 s
