Assertion : Super-oxides of alkali metals are para-magnetic.
Reason : Super-oxides contain the ion `O_(2)^(-)` which has one unpaired electron.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.
