The following table lists the intracellular osmolality concentrations of four osmoconforming organisms that are known to mimic the osmotic conditions of their surroundings.

Which of the following statements best describes the insides of these organisms compared to the environment in the tank when they reach osmoconformity?
(A) Due to the influx of water into the organisms’ cells, the organisms’ insides are hypertonic when compared to the tank.
(B) Compared to the tank, the loss of water out of the organisms’ cells makes the organisms’ insides hypotonic.
(C) The organisms’ insides are isotonic since the intracellular osmolality concentrations match the osmolality concentrations of the tank.
(D) The flow of water into and out of the organisms’ insides causes the cells to be retrotonic.
