Best answer
The correct choice is (b) False

The best explanation: Magnesium is mainly distinguished by its low density, which is nearly about 25% of steel and about 60% of the aluminium metal. This property makes magnesium to use for very lightweight construction. In expensive cars, it is highly used in the construction of crankcase and in other parts to increase power to weight ratio.
