Final answer:
The least amount of acceleration would occur when a smaller force acts on a larger mass.
Step-by-step explanation:
The least amount of acceleration would occur when a smaller force acts on a larger mass. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. Therefore, a 5-newton force acting on a 25-kilogram block (option D) would produce the least amount of acceleration compared to the other scenarios.
