A)You won't feel any change and will have no way to know that you've left Earth.
B)You'll feel a force that will cause your head to repeatedly bang into the ceiling.
C)You'll know that you left Earth because when you drop a ball it will fall sideways.

Einstein's equivalence principle states that the effects of gravity are indistinguishable from the effects of acceleration. Therefore, if the room accelerates at 1g, it would mimic the gravitational pull of Earth, making it impossible to discern that you've left Earth based solely on physical sensations or observations within the room.
