To investigate the effect of salt water on a cell, a researcher places one cell sample in freshwater and a second cell sample in salt water. After six hours, the researcher observes and sketches the two cells as shown. What change in the cells occurred during the six hours the cells remained undisturbed?

A:Osmosis occurred in the salt water cell sample because the water from inside the cell moved out of the cell to a lower concentration, causing the cell to shrink.
B: Osmosis occurred in the freshwater cell sample because the water from outside the cell moved into the cell to a higher concentration, causing the cell to grow.
C: Osmosis occurred in the salt water cell sample because the salt from outside the cell moved into the cell to a lower concentration, causing the cell to shrink.
D: Osmosis occurred in the freshwater cell sample because the salt from inside the cell moved out of the cell to a higher concentration, causing the cell to grow.
