A Correct answer
Explanation

We know that as per the molecular orbital theory,O2 contains two electrons in the anti-bonding orbital if we have a look on the molecular orbital diagram of O2 and hence, it is paramagnetic in nature. Also statement 2 is correct that O2 contains two unpaired electrons in anti bonding orbital, and statement 2 is correct explanation of statement 1 as discussed above.
