Answer:

C. The balloon will rise in the air.

Explanation:

It is already established that helium is lighter than ordinary air. By gravity, the heavier things will drop down, while the lighter will push itself upwards. If a balloon is filled with helium, then the oxygen would be pushed downwards as the helium pushes the balloon higher.
