The correct answer is A. No because it is not speeding up.
Explanation
Acceleration is a verb that refers to the action of increasing speed. Therefore, if the boat in the photo is moving at a constant speed of twenty miles per hour, this means that it will always move at the same speed, so it will not increase or decrease its speed. So the ship is not accelerating, it is just going at the same speed. According to the above, the correct answer is A. No because it is not speeding up.
