Which of the following is NOT considered an electrolyte?

Explanation:
An electrolyte is a substance that dissociates into ions in solution and conducts electrical current in body fluids. Sodium, chloride, potassium, and calcium all do this, forming Na+, Cl−, K+, and Ca2+. These ions are essential for nerve impulses, muscle contraction, fluid balance, and many other physiological processes. Because each of these forms ions in solution, all listed substances are electrolytes. If a question asks for something not an electrolyte, the correct idea would be that none of these fit—their common presence as electrolytes means there isn’t a non-electrolyte among them.
