It's the sodium ion.
When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.
Answer:
The correct option is A. The cell is sitting in a hypertonic solution.
Explanation:
A hypertonic solution is a solution in which there are more number of solutes present in the solution than inside the cell. The solutes then tend to pass into the cell through diffusion from the solution.
As it can be seen in the diagram, the concentration of salt is more in the solution i.e 40%. Hence, the salt from the solution enters into the cell by diffusion and has a concentration of 10% inside the cell which shows the cell to be placed in a hypertonic environment.

2)Keep more fruits, low-fat dairy products (low-fat milk and low-fat yogurt), vegetables, and whole-grain foods at home and at work. Focus on adding healthy food to your diet, rather than just taking unhealthy foods away. Try to eat a family meal every day at the kitchen or dining table.
3)Biomacromolecules are large biological polymers, such as nucleic acids, proteins and carbohydrates, that are made up of monomers linked together. For example, proteins are composed of monomers called amino acids.
4)The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed
5)Cellular metabolism is the set of chemical reactions that occur in living organisms in order to maintain life. Cellular metabolism involves complex sequences of controlled biochemical reactions, better known as metabolic pathways.
6)Sugars, such as galactose, fructose, and glycogen, are catabolized into new products in order to enter the glycolytic pathway.
I would say C or D
