The substance that has been acting as an electrolyte from the given molecules is sulfuric acid. Thus, option 4 is correct.
Electrolytes have been defined as the chemical substances that has been dissociated into constituent ions when dissolved in the aqueous solution.
Identifying electrolytes
The ionic compounds are bounded by weak intermolecular forces and are dissociated into ions in the solution. Thus, the compounds are given as electrolytes.
The covalent bonded molecular atoms are not dissociated into ions and are not considered as electrolytes.

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.

Explanation:
Most of the carbon compound are convalent in nature and all of the electrons participates in bond formation as such there is no free electrons left to conduct electricity. Moreover carbon compound doesn't readily dissociates to form ions, which conduct electricity. Hence carbon compound are poor conductor of electricity.
Answer:
It is because all the valence electrons are used to form covalent bonds. So, there will be no electrons left to flow the electric current through them.

Answer:
c) The mass is the same
Explanation:
According to the Law of Conservation of Mass, the total mass of the reactants in a chemical reaction is always equal to the total mass of the products formed. This means that the total mass of the reactants and the total mass of the products will always be the same.
