During a practical Chemistry class, 1st-year high school students carried out a series of experiments involving inorganic substances commonly found in laboratories. One of these experiments consisted of observing the behavior of some substance samples when dissolved in water. One student noticed that when adding one of the solid substances to a beaker containing water, the resulting solution started to conduct electricity. Considering the properties of inorganic substances and the behavior of acids in aqueous solution, what is the most likely classification of the substance added to the beaker?

The substance added to the beaker is an oxide, as oxides, when in contact with water, react to form bases and acids, enabling the conduction of electricity.

The substance added to the beaker is an acid, as acids are electrolytes that, in aqueous solution, release H⁺ ions, resulting in a solution capable of conducting electricity.

The substance added to the beaker is a molecular compound, as pure molecular compounds in aqueous solution generally do not conduct electricity due to the absence of free ions.

The substance added to the beaker is a base, as bases, when dissolved in water, release OH⁻ ions, enabling the conduction of electricity.

The substance added to the beaker is a salt, as salts are substances that, in aqueous solution, dissociate into cations and anions, allowing the conduction of electricity.
