Answer 2

(b) is the correct option.

Magnesium is largely derived from ocean water.

• The ocean has a large quantity of all kinds of metals but these are so diffused in the ocean water they are impossible to extract.
• Magnesium is however present in the amount of 1300 ppm, making it easier to extract and purify when compared to others.
• In some countries, the main source of magnesium is salty water and the ocean.
