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

Carrot in 0.2M salt solution

Explanation:

Carrot cuts put in 0.2M salt answer for a few hours gets flabby (limp). Carrot cuts set in freshwater for a few hours gets turgid  (firm). From this, we can conclude that such as.   Freshwater is hypertonic and the salt arrangement is hypotonic to the cells of the carrot cuts. Freshwater and salt arrangement are both hypotonic to the cells of the carrot cuts.  Freshwater is isotonic and the salt arrangement is hypertonic to the cells of the carrot cuts.  Freshwater is hypotonic and the salt arrangement is hypertonic to the cells of the carrot cuts.  Freshwater and the salt arrangement are both hypertonic to the cells of the carrot cuts.
