Answer»

The correct answer is (a) Oxygen

To EXPLAIN I would say: Oxygen constitutes about 46-47% of the Earth’s CRUST, FOLLOWED by Silicon at 27-28%. Oxygen is predominantly present as a gas in air and several metallic COMPOUNDS that constitute a metal ore (in the form of oxides). Apart from these, Aluminum is the most abundant metal in the Earth’s crust followed by Iron.
