b. less water would need to be excreted by the kidneys.
c. they don't have kidneys.
d. their cells would eventually swell.
The best answer is A.
Unlike marine animals such as fish, land vertebrates do not have mechanisms to excrete high salt content. Their excretory organs namely the kidneys are not designed to handle concentrated salt content.
Therefore if high salt content is retained in the body, then osmotic imbalance in cells of land vertebrates would occur with the cells losing water because they would be hypotonic to their immediate surrounding and eventually die.
Marine fish are able to maintain osmotic balance in the sea water because they have specialized cells in their gills that actively eliminate salt and these fishes do not absorb any salt from the water they drink.

The hemophilic father has only one X chromosome and they will transfer this affected X chromosome to their daughters and none of their sons. Since, sons receive Y chromosome from their father.
Thus, the correct answer is option (C).
