B. An open system exchanges energy with its surroundings !!!
An open system is unchanging >> this is impossible .. as long as it exchanges matter and energy it must change ..
An open system is unaffected by outside objects >> its wrong coz it can be affected ..

It's B.
A closed system means that the energy stays inside (or outside) the system. An open system has no barriers, and is therefore "open" to the exchange of energy with its surroundings.
P.S. Why is there no A?

Sorry to be judgemental, but it doesn't say much about you when you so blatantly post your homework here and wait for others to do it for you.
