Answer:
The correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.
Explanation:
The plant cell has a rigid cell wall that provides support to the plant cell that is not the case in the animals as they lack the cell wall. The low tidewater is an example of the hypotonic solution as it has fewer solutes than the plant cells or animal cells.
When a plant cell is in freshwater it takes up the water with the help of osmosis and begins to swell but the cell wall does not let it burst and become turgid.
Thus, the correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.

- But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.
Types of tissues attack:-
- Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.
- Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.
Result of immune system attack:-
- Damaged myelin sheath stop forming whIte matter of central nervous system.
- Hence disrupt coordinating communication between different brain regions.
Signs and symptoms:- vary from person to person
- Diminished eyesight.
- Disrupt motor coordination.
- Weak sensory perception.
- Fatigue and dizziness.
