Because Oxygen Has a Low Solubility Coefficient in Water

Because oxygen has a low solubility coefficient in water,

A) it is easily dissolved in water and requires only a slight partial pressure gradient to enter the water.
B) it is easily dissolved in water and the partial pressure gradient is irrelevant to its solubilty.
C) it is not easily dissolved in water and requires a steep partial pressure gradient to enter the water.
D) it is impossible to dissolve oxygen into water unless the partial pressure gradient is very minor.
