D Correct answer
Explanation

Statement (1) is wrong. When a truck is fully loaded, its centre of gravity will be raised making it unstable. When taking a sharp turn the vertical line through the centre of gravity will fall outside the base of support, and the truck may topple over. Statement (2) is also incorrect. While throwing a ball upwards, the acceleration remains the constant.
