According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. This means that the pumpkin exerts a force of 50 newtons on the child, which is equal in magnitude but opposite in direction to the child's force on the pumpkin. Therefore, the correct answer is B, 50 newtons.
