A. electrolysis of their molten chloride; A.

B. electrolysis of their molten oxides; and (c) reduction by aluminum B.

C. Carbon dioxide reduction C.

D. None of these D.

Correct Answer: A সঠিক উত্তর: A

Explanation ব্যাখ্যা

Highly reactive metals like sodium, potassium, and magnesium are found high up in the reactivity series, meaning they cannot be extracted by reduction with carbon or aluminum because they are more reactive than these reducing agents.

Correct extraction method:
These metals are extracted by the electrolysis of their molten chlorides (or sometimes molten oxides, but chlorides are more common and efficient industrially).
For example:
Sodium is extracted by electrolysis of molten NaCl.
Magnesium is extracted by electrolysis of molten MgCl₂.
