Sure, let me try to help you on this one.
Out of these four things, the least distinctive for the living thing would probably be "movement".
Metabolism is a strong sign of a living thing since it's the exact same thing keeping it alive.
Cellular organization is definitely a #1 sign of a thing being alive. Things that are not alive simply don't have cells!
Homeostasis is similar to metabolism - it's a sign of a thing being alive because it's the process that keeps it alive and balanced.
Movement; however, is debatable. Everything can move, not only living things. For example, water in the xylem going upwards is one example. Water, nor xylem are alive.
Answer: movement is the least distinctive characteristic of a living thing.
