Which statement describes a disadvantage of a passive prosthesis?

Explanation:
The main idea is that a passive prosthesis lacks active movement and grasping ability. Because it has no powered actuators to open or close the fingers, it cannot actively pick up or manipulate objects, which is a real functional limitation in daily tasks. The other statements describe features not characteristic of passive devices—automated gripping implies self-initiated grip, advanced sensory feedback implies sensors and actuation beyond a passive version, and battery changes relate to powered devices—so they don’t describe a drawback of a passive prosthesis.
