Explanation:
Correct option is B)
Oxygen is the most abundant element on the surface of earth.
In the free form, it is present in the air as gas (21% by volume).
In the combined form, it is found as water, oxides and oxysalts. Th latter two constitute 46.6% of the earth's crust.
Oxygen contains unpaired electrons. Hence, it is paramagnetic.
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
