Quizplus · Accepted Answer

When an acid reacts with an active metal, the metal is oxidized, and the hydrogen ions in the acid are reduced to hydrogen gas. This can be represented as the following balanced equation: 
2HCl + Mg → MgCl2 + H2 
In this reaction, magnesium is oxidized (loses electrons) and hydrogen ions in hydrochloric acid are reduced (gain electrons) to form hydrogen gas. Therefore, both options A and B are incomplete or incorrect. The correct answer is C, as it includes both the oxidation of the metal and the reduction of the hydrogen ions in the acid.
