The Basic Principles of Body Mechanics Require All of the Following

The basic principles of body mechanics require all of the following except:

A) maintain a stable center of gravity by keeping your center of gravity low and your back straight and bending your hips and knees.
B) maintain a strong base of support by keeping your feet apart, placing one foot slightly ahead of the other with the toes pointing in the direction of activity.
C) when lifting, flex your hips to absorb jolts, and turn with your feet instead of your knees.
D) maintain a center of gravity by keeping your back straight and any objects being lifted close to your body.
