After 3.00 seconds, the ball would have reached the highest point in its trajectory and started to fall down due to gravity. The velocity at this point would be downward and equal to the acceleration due to gravity, which is 9.80 m/s^2. Therefore, the correct answer is 9.80 m/s down (choice D).

A Ball Is Thrown Upward at a Velocity of 19
