    Electrolyte is any species which when dissolved in solvent particularly water dissociates into cations and anions. Electrolytes are conductors of electricity. In given options;

    CCl₄ (Tetrachloromethane) is a covalent compound. And it doesn't dissociate to any cation or anion. So it is not electrolyte.

    SiO₂ (Silicon Dioxide) is also covalent in nature and exist in giant framework. It is not electrolyte.

    Glucose (C₆H₁₂O₆) is also covalent compound. And doesn't produced any ion in water, hence it is not electrolyte.

    H₂SO₄ (Sulfuric acid) is Electrolyte. When it is dissolved in water it produces H⁺ and SO₄²⁻ ions as follow,

    H₂SO₄ → 2 H⁺ (aq₎ + SO₄²⁻ (aq₎

    Result:

    H₂SO₄ is electrolyte.
