Carrot slices placed in a 0.2 M salt solution for several hours become flaccid (limp).Carrot slices placed in fresh water for several hours become turgid (stiff).From this we can deduce that

The observation that the carrot slices become flaccid when placed in the 0.2 M salt solution suggests that the solution is hypertonic to the cells of the carrot slices. This means that the solution has a higher solute concentration than the cells, causing water to move out of the cells and into the solution, resulting in the cells becoming flaccid. 
Conversely, the observation that the carrot slices become turgid when placed in fresh water suggests that the water is hypotonic to the cells of the carrot slices. This means that the water has a lower solute concentration than the cells, causing water to move into the cells, resulting in the cells becoming turgid or stiff. 
Therefore, the best choice is D, which states that the fresh water is hypotonic and the salt solution is hypertonic to the cells of the carrot slices.
