Answer
A) A twisting motion that stretches a disc.
Explanation
## Step 1: Analyze the ChoicesIn order to solve this problem, we must first analyze and define each of the given choices: A) A twisting motion that stretches a disc – This describes a motion that involves rotation or torsion resulting in stretching of the spinal disc. B) A downward force that compresses – This suggests a vertical, compressive force that compacts or minimizes the space (this happens when carrying a heavy backpack, for example). C) An application of compression on tension on the other – This choice seems to refer to a situation where there's a dynamic between compression (decrease in dimension) and tension (stretching or elongation) being applied simultaneously or alternately. Any such application is not necessarily specific to 'torsional' force.## Step 2: Identify the Correct ChoiceWith the definitions detailed, determining the choice that best describes 'torsional force' as it acts on the spine becomes clear, torsional force is generally associated with rotation or twisting in relation to an axis; in the case of the spine, it is usually about the vertical axis formed by the spinal column itself. Given this understanding, choice A—"A twisting motion that stretches a disc"— best describes the effect of torsional force on the spine.
