The electrolyte represented by the symbol Na is:

Explanation:
Electrolytes are charged particles that conduct electricity in body fluids. The symbol Na corresponds to sodium, the main extracellular cation. The name Na comes from natrium, the element’s historical name, which is why the symbol doesn’t match the common name. Sodium helps regulate extracellular fluid volume and osmolarity and supports nerve impulses and muscle contractions via the sodium–potassium pump. Among the options, only sodium uses the symbol Na; potassium is K, chloride is Cl, and glucose is a non-electrolyte that does not ionize in solution.
