a. it decreases your chance of injury.

b. it increases your contraction rate.

c. it decreases your flexibility.

d. it increases your bone density.

Explanation:

• Option A: Impact exercises like jumping rope can actually increase injury risk if not done properly, so A is incorrect.
• Option B: Contraction rate (of muscles) isn't directly increased by jumping rope in a typical sense related to this question's context, so B is incorrect.
• Option C: Jumping rope doesn't decrease flexibility; in fact, it can help with some aspects of mobility, so C is incorrect.
• Option D: Impact exercises (weight - bearing exercises) like jumping rope stimulate bone growth and increase bone density as the bones adapt to the stress of the impact.
