The electrolyte represented by the symbol K is:

Explanation:
Potassium is the electrolyte denoted by the symbol K. Electrolytes are charged particles in body fluids that conduct electricity when dissolved, and potassium specifically exists as the K+ ion. It is the major intracellular cation and plays a key role in maintaining the resting membrane potential and in nerve and muscle (including heart) signaling. That’s why K is potassium. The other possibilities don’t fit: chloride would be Cl-; sodium would be Na+; glucose is a sugar that does not dissociate into ions in solution, so it’s not an electrolyte.
