Explanation:

Question 20

Correct lifting technique involves bending at the knees (to use leg muscles) rather than rounding the back or bending at the waist (which strains the back). Sharma rounding her back is incorrect. Peter bending at his waist is incorrect. Jack bending at his knees is correct.

In a neutral spine position, the ears, shoulders, and hips should be in a straight line. A "C" shape would be a rounded (kyphotic) spine, and an "S" shape is the natural curve but not for neutral alignment in this context (neutral spine is a straight alignment of these points for proper posture during lifting etc.).

The green zone (or green light) in lifting terminology means you can lift the most weight with minimum injury risk. Yellow is moderate, red is high risk (should not lift or use extreme caution). So the correct option is Green.

Answer:

Jack bends at his knees
