Answer: A . The cell will swell because water will enter it.
Explanation:
The cell will swell because it will undergo a process known as Osmosis.
Osmosis is a process where water molecules move from an area with a higher concentration of water to an area with a lower concentration across a semi-permeable membrane.
That semi-permeable membrane in this case is the cell membrane and because the cell has less water than the solution, water will flow into the cell thereby causing it to swell.
