Answer:
Option-B, Ca(OH)₂ is the correct answer.
Step-by-step explanation:
By definition Electrolytes are those compounds which when poured in polar solvents dissociate into a positively charged specie called Cation and a negatively charged specie called an Anion. These ions have the potential to conduct electricity.
So Ca(OH)₂ is dissolved in water it produces Ca⁺² cation and OH⁻ anions. So it acts as an Electrolyte.
While, C₆H₁₂O₆ (Glucose), C₁₂H₂₂O₁₁ (Table Sugar) and CH₃OH (Methanol) are covalent compounds and does not produce any positive or negative ions when dissolved in water.
