A student was studying osmosis. She performed an investigation in which she soaked sample cells in a sucrose solution. She weighed the samples every 10 minutes and recorded the mass. Below is a graph of her results. What should she conclude about sample C? Captionless Image

The cells in sample C were composed of a sucrose solution.

The cells in sample C were hypotonic with the sucrose solution.

The cells in sample C were isotonic with the sucrose solution.

The cells in sample C were hypertonic with the sucrose solution.
