Prosthesis is used to replace a part of the patient. Some prosthesis powered by external source that allow it to do some degree of movement. Passive prosthesis doesn't have electronic or mechanic part, which makes their function is more to be cosmetic than function.
Answer:
The correct answer is option a. "A passive prosthesis".
Explanation:
A passive prosthesis is basically a costemic restoration because this type of prosthesis does not serve a practical purpose but only cosmetic. Passive prosthesis do not need external power sources since they are not charged to have movement. Passive prosthesis are useful for patients who don't need precise movement in the hand, arm or leg that they want to replace.
