I don’t understand why this is the correct answer. I thought hypertonic is when the inside of the cell has a lower solute concentration so the water leaves the cell. Could someone please explain?

Hypotonic means lower solution, so more water. Hypertonic means higher solution, so less water
The solution is hypertonic not the cell. Easy mistake to make don’t stress
Everyone has already explained to you, but allow me to share with you something that might help.
Remember that "hyper-" means above/beyond. When someone is hyperventilating, they are breathing above/beyond the normal amount. "Hypo-" is the opposite: Under/beneath.
Tonicity is the concentration of something.
Thus, hyper tonic is higher concentration, and hypo tonic is lower concentration.
Hyper think sugar in blood makes you hyper Hypo is opposite of that

Bro water and solute concentrations are reversly related. This means more water concentration is less solute concentration. This means more solute = less water. Less solute = more water.
In the example above, they said its lower solute. Lower solute = more water. More water = hypotonic. Hypotonic = water leaves from the cell and it shrinks.
hyPO- is low! oh no, i'm gonna blow! (water swells) HYper- is high! water goes bye
is how i remember it.
Ooooh, that's a nice trick, thanks!
