Answer:

A. It will continue to concentrate inside the cell.

Step-by-step explanation:

Due to the higher concentration of oxygen molecules on the inside, oxygen molecules of the outside move to the inside and the more the oxygen molecules move inside the higher the concentration of the oxygen molecules on the inside.
