AI Explanation

The correct answer is D. The proper technique for lifting an object is to bend the knees and grasp the object firmly, keep the back straight, then lift the object by straightening the legs while keeping the object close to the body. This distributes the weight and stress of the lift through the stronger leg muscles rather than the back, which helps prevent back injuries. The other options are incorrect because they either keep the legs straight (A and C), which puts more strain on the back, or keep the object away from the body (A and B), which requires more effort and leverage to lift and move the object.
