I think the first statement is true; while the second statement is false. It is true that drinking sea water would cause a rise in the osmotic pressure of the extracellular fluid because sea water will be hypertonic (salty water) to the extracellular fluid therefore water will move from the extracellular fluid osmotically creating an a rise in osmotic pressure. The whole effect won't make water leave the blood capillaries.
The answer would be D. Empiricality. Scientific Method can not, and will not deal with studies that are either for logic or for theism. This field may be beyond the scientific confirmability, meaning, it can not be proven by science, one example of this is the existence of a primary mover, or a God.
