Rehabilitation exercises should be used for

a. muscle strength and size training
b. weight maintenance training
c. muscle endurance training
d. restoring a weak or injured body part

absolute strength refers to the maximum force exerted by a body irrespective of body size. relative strength on the other hand is the force exerted by a body in relation to muscle size or body weight.

so the answer is: c. absolute strength measures strength regardless of your body size, while relative strength measures strength adjusted for your weight.
