The cells of a fish are about 0.85% salt. One liter of water is about 1,000 grams. Solution A contains 70 grams of salt in 5 liters of water, solution B contains 120 grams of salt in 10 liters of water, and solution C contains 50 grams of salt in 10 liters of water. Which solution(s) is(are) hyperosmotic relative to the fish's cells?
A) Solution A only
B) Solution B only
C) Both solution A and solution B
D) Both solution B and solution C

Solution A has a concentration of 1.4% salt (70g/5000g), and solution B has a concentration of 1.2% salt (120g/10000g). Both are higher than the fish's cell concentration of 0.85% salt, making them hyperosmotic. Solution C has a concentration of 0.5% salt (50g/10000g), which is lower than the fish's cells.
