Of the following which can be extracted by the electrolytic reduction of their salts?

Correct answer: B. Mg and Al

A. Ag
B. Mg and Al
C. Ca
D. All

Explanation

Magnesium and aluminium can be obtained by the electrolytic reduction of their ores respectively, as they are highly reactive metals with stable oxides that require electrolytic reduction. Silver (Ag) and Calcium (Ca) are not extracted by electrolytic reduction of their salts. Therefore, the correct answer is option B.
