According to Newton's second law of motion, acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass. Therefore, when the mass of the object becomes twice as much, the acceleration would be halved. This can be mathematically represented as a = F/m. If the force remains constant, and m doubles, then the acceleration would be a/2 (halved). Therefore, the correct answer is D) halves.
