When a cell is placed in a solution, the movement of water molecules across the cell membrane depends on the concentration of solutes inside and outside the cell. If the concentration of solutes outside the cell is higher than inside the cell, the solution is hypertonic. In such a solution, water molecules move from the area of higher concentration (inside the cell) to the area of lower concentration (outside the cell) by a process called osmosis. As a result, the cell loses water and gets dehydrated.
In the given scenario, the sugar solution outside the cell is hypertonic as the concentration of solutes (sugar molecules) is higher than inside the cell. Therefore, water molecules move out of the cell, causing it to shrink or get dehydrated.

Hypertonic solution means more solute ie., high concentration of solute & low concentration of water.
osmosis - diffusion of water from high concentration of water to the low concentration of water .
when compared to the hypertonic sugar solution , cell has high concentration of water .so , when cell is kept in that hypertonic sugar solution , movement of water is from cell to the sugar solution . thus the cell loses water and becomes dehydrated.

Explanation:
When a cell is placed in a sugar solution, the movement of water molecules occurs through a process called osmosis. Osmosis is the movement of solvent molecules (in this case, water) from an area of lower solute concentration to an area of higher solute concentration, across a semi-permeable membrane.
Hypertonic Solution:
A hypertonic solution is a solution that has a higher solute concentration compared to the cell. In this case, the sugar solution has a higher solute concentration than the cell. When a cell is placed in a hypertonic solution, water molecules move out of the cell through osmosis, leading to the cell becoming dehydrated.
Dehydration of the Cell:
When a cell is placed in a hypertonic solution, the concentration of solutes outside the cell is higher than inside the cell. As a result, water molecules move out of the cell to equalize the concentration on both sides of the cell membrane. This leads to the cell losing water and becoming dehydrated.
Other Options:
- Hypotonic Solution: A hypotonic solution has a lower solute concentration compared to the cell. In a hypotonic solution, water molecules move into the cell through osmosis, causing the cell to swell or even burst. Since the given scenario describes the cell getting dehydrated, it cannot be a hypotonic solution.
- Isotonic Solution: An isotonic solution has an equal solute concentration compared to the cell. In an isotonic solution, there is no net movement of water molecules, and the cell remains in a stable state. Since the given scenario describes the cell getting dehydrated, it cannot be an isotonic solution.
- None of the Above: The correct answer is option B, hypertonic solution, as explained above. The other options do not describe the given scenario of the cell getting dehydrated.
In conclusion, when a cell is placed in a sugar solution and gets dehydrated, the solution can be classified as a hypertonic solution.
