Bone strengthening refers to activities that promote bone growth and increase the strength of your bones. Option A is the correct answer. These activities typically involve applying a force or stress on your bones, which stimulates bone cells to increase production and density, making them stronger.

To determine the correct answer, you can break down the question and analyze each option:

A. Activities that produce a force on the bones that promote bone growth and strength: This option accurately describes bone strengthening activities by emphasizing the force applied to the bones, which results in increased bone growth and strength.

B. Activities that produce greater elasticity of joints: This option refers to activities that enhance joint flexibility rather than directly promoting bone strengthening.

C. Activities that heal injuries and diseases associated with the bones: This option describes activities that aid in the recovery and treatment of bone injuries or diseases, which is not necessarily synonymous with bone strengthening.

D. None of the above: This option implies that none of the given options accurately describe bone strengthening activities, which is incorrect.

Therefore, the correct answer is A. Activities that produce a force on the bones that promote bone growth and strength.
